+What:		/sys/kernel/uids/<uid>/cpu_shares
+Date:		December 2007
+Contact:	Dhaval Giani <dhaval@linux.vnet.ibm.com>
+		Srivatsa Vaddagiri <vatsa@linux.vnet.ibm.com>
+Description:
+		The /sys/kernel/uids/<uid>/cpu_shares tunable is used
+		to set the cpu bandwidth a user is allowed. This is a
+		propotional value. What that means is that if there
+		are two users logged in, each with an equal number of
+		shares, then they will get equal CPU bandwidth. Another
+		example would be, if User A has shares = 1024 and user
+		B has shares = 2048, User B will get twice the CPU
+		bandwidth user A will. For more details refer

+**** 32-bit BOOT PROTOCOL
+
+For machine with some new BIOS other than legacy BIOS, such as EFI,
+LinuxBIOS, etc, and kexec, the 16-bit real mode setup code in kernel
+based on legacy BIOS can not be used, so a 32-bit boot protocol needs
+to be defined.
+
+In 32-bit boot protocol, the first step in loading a Linux kernel
+should be to setup the boot parameters (struct boot_params,
+traditionally known as "zero page"). The memory for struct boot_params
+should be allocated and initialized to all zero. Then the setup header
+from offset 0x01f1 of kernel image on should be loaded into struct
+boot_params and examined. The end of setup header can be calculated as
+follow:
+
+	0x0202 + byte value at offset 0x0201
+
+In addition to read/modify/write the setup header of the struct
+boot_params as that of 16-bit boot protocol, the boot loader should
+also fill the additional fields of the struct boot_params as that
+described in zero-page.txt.
+
+After setupping the struct boot_params, the boot loader can load the
+32/64-bit kernel in the same way as that of 16-bit boot protocol.
+
+In 32-bit boot protocol, the kernel is started by jumping to the
+32-bit kernel entry point, which is the start address of loaded
+32/64-bit kernel.
+
+At entry, the CPU must be in 32-bit protected mode with paging
+disabled; a GDT must be loaded with the descriptors for selectors
+__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat
+segment; __BOOS_CS must have execute/read permission, and __BOOT_DS
+must have read/write permission; CS must be __BOOT_CS and DS, ES, SS
+must be __BOOT_DS; interrupt must be disabled; %esi must hold the base
+address of the struct boot_params; %ebp, %edi and %ebx must be zero.

+소개

+
+커� 내부� �터페�스가 바뀌는 것� 걱정하며 커� 드��버를 작성하고
+싶어하는 사람� 정� ��한 사람�다. 세�� 대다수� 사람들� � �터페�스를
+보지못할 것�며 전혀 걱정하지� 않는다.
+
+먼저, 나는 closed 소스, hidden 소스, binary blobs, 소스 wrappers, �는 GPL로
+배��었지만 소스 코드를 갖고 있지 않� 커� 드��버들� 설명하는 어떤 다른
+용어들� 관한 어떤 법�� 문제� 관해서는 언급하지 않� 것�다. 어떤 법��
+질문들� 가지고 있다면 변호사와 연�하�. 나는 프로그래머�므로 여기서 기술��
+문제들만� 설명하려고 한다. (법�� 문제를 경시하는 것� 아니다. 그런 문제들�
+엄연히 현실� 있고 여러분들� 항� 그 문제들� ��하고 있� 필요는 있다.)
+
+�, �가지� 주요 주제가 있다. 바�너리 커� �터페�스들과 변하지 않는
+커� 소스 �터페�들. 그것들� 서로 �존성� 가지고 있지만 바�너리
+문제를 먼저 풀고 넘어갈 것�다.
+
+
+
+바�너리 커� �터페�스
+------------------------
+우리가 변하지 않는 커� 소스 �터페�스를 가지고 있다고 가정하�. 그러면
+바�너리 �터페�스 �한 �연�으로 변하지 않�까? 틀렸다. 리눅스 커��
+관한 다� 사실들� ��해보�.
+   - 여러분들� 사용하는 C 컴파�러� 버젼� 따� 다른 커� �료 구조들�
+     다른 alignmnet들� 갖게 �것�고 다른 방법으로(함수들� inline으로
+     했��, 아니�) 다른 함수들� �함하는 것� 가능한다. 중요한 것�
+     개별�� 함수 구성� 아니� �료 구조 패딩� 달�진다는 ��다.
+   - 여러분� 선�한 커� 빌드 옵션� 따�서 커�� 다양한 것들� 가정할
+     수 있다.
+      - 다른 구조체들� 다른 필드들� �함할 수 있다.
+      - 몇몇 함수들� 전혀 구현�지 않� 수� 있다(즉, 몇몇 lock들�
+        non-SMP 빌드�서는 사�져 버릴수� 있다).
+      - 커�내� 메모리는 build optoin들� 따� 다른 방법으로 align�수
+        있다.
+      - 리눅스는 많� 다양한 프로세서 아키���서 실행�다. 한 아키���
+        바�너리 드��버를 다른 아키���서 정��으로 실행시킬 방법�
+        없다.
+
+커�� 빌드했� C 컴파�러와 정확하게 같� 것� 사용하고 정확하게 같�
+커� 구성(configuration)� 사용하여 여러분들� 모듈� 빌드하면 간단히
+많� 문제들� 해결할 수 있다. �렇게 하는 것� 여러분들� 하나� 리눅스
+배��� 하나� 배� 버젼� 위한 모듈만� 제공한다면 별� 아� 것�다.
+그러나 �기 다른 리눅스 배��마다 한번씩 빌드하는 수를 � 리눅스 배��마다
+제공하는 다른 릴리즈� 수와 곱하게 �면 �번�는 � 릴리즈들� 다른 빌드
+옵션� 악몽과 마주하게  것�다. �한 � 리눅스 배��들� 다른 하드웨어
+종류�(다른 프로세서 타입과 다른 옵션들) 맞춰져 있는 많� 다른 커�들�
+배�한다. 그러므로 한번� 배��서조차 여러분들� 모듈� 여러 버젼�
+만들 필요가 있다.
+
+나를 믿어�. 여러분들� �러한 종류� 배�를 지�하려고 시�한다면 시간�
+지나면 미칠지경� � 것�다. 난 �러한 것� 오래전� 아주 어렵게 배웠다...

+
+변하지않는 커� 소스 �터페�스들
+---------------------------------
+
+리눅스 커� 드��버를 계�해서 메� 커� 트리� 반�하지 않고
+유지보수하려고 하는 사름들과 � 문제를 논�하게 �면 훨씬 �
+"논란� 여지가 많�" 주제가 � 것�다.
+
+리눅스 커� 개발� �임없� 빠른 ��로 �루어지고 있으며 결코
+�슨해진 �� 없다. 커� 개발�들� 현재 �터페�스들�서 버그를
+발견하거나 무엇�가 할수 있는 � 좋� 방법� 찾게 �었다고 하�.
+그들� 발견한 것� 실행한다면 아마� � 잘 �작하�� 현재 �터페�스들�
+수정하게 � 것�다. 그들� 그런 �� 하게�면 함수 �름들� 변하게 �고,
+구조체들� 늘어나거나 줄어들게 �고, 함수 파�미터들� 재작업� 것�다.
+�러한 �� 발��면 커� 내� � �터페�스를 사용했� �스턴스들� �시�
+수정� 것�며 �러한 과정� 모든 것� 계�해서 올바르게 �작할 것��는
+것� 보장한다.
+
+�러한 것� 한 예로�, 커� 내부� USB �터페�스들� � 서브시스템�
+�긴 �후로 �어� 3번� 다른 재작업� 겪었다. � 재작업들� 많� 다른
+문제들� 풀었다.
+   - ��터 스트림들� �기�� 모��서 비�기�� 모�로� 변화. �것�
+     많� 드��버들� 복잡성� 줄�고 처리량� 향�시켜 현재는 거� 모든
+     USB 장치들� 거� 최대 ��로 실행�고 있다.
+   - USB 드��버가 USB 코어로부터 ��터 패킷들� 할당받로� 한 변경으로
+     �해서 지금� 모든 드��버들� 많� 문서화� �드�� 수정하기 위하여
+     USB 코어�게 � 많� 정보를 제공해야만 한다.
+
+�것� 오랫�안 �신� 오래� USB �터페�스들� 유지해야 하는 closed 운�체제들과는
+완전히 반대�는 것�다. closed� 운�체제들� 새로운 개발�들�게 우연히 낡�
+�터페�스를 사용하게 할 기회를 주게�며, �절하지 못한 방법으로 처리하게 �어
+운�체제� 안정성� 해치는 문제를 야기하게 �다.
+
+� �가지� 예들 모�, 모든 개발�들� 꼭 �루어져야 하는 중요한 변화들��고
+��를 하였고 비�� �� 고통으로 변경�어졌다. 리눅스가 변하지 않는 소스
+�터페�스를 고집한다면, 새로운 �터페�스가 만들어지게 �며 반면 기존� 오래�
+것들, 그리고 깨진 것들� 계�해서 유지�어야 하며 �러한 �들� USB 개발�들�게
+� 다른 �거리를 주게 �다. 모든 리눅스 USB 개발�들�게 �신� 그들� 업무를
+마친 후 시간� 투�하여 아무 �� 없는 무료 봉사를 해달�고 하는 것� 가능성�
+�박한 ��다.
+
+보안 문제 역시 리눅스�게는 매우 중요하다. 보안 문제가 발견�면 그것�
+매우 짧� 시간 안� 수정�다. 보안 문제는 그 문제를 해결하기 위하여
+여러번 내부 커� �터페�스들� 재작업하게 만들었다. �러한 문제가
+발�하였� 때 그 �터페�스들� 사용하는 모든 드��버들� �시�
+수정�어 보안 문제가 앞으로 갑작스럽게 �기지는 않� 것��는 것�
+보장한다. 내부 �터페�스들� 변경� 허��지 않으면 �러한 종류� 보안
+문제를 수정하고 그것� 다시 발�하지 않� 것��고 보장하는 것� 가능하지
+않� 것�다.
+
+커� �터페�스들� 계�해서 정리�고 있다. 현재 �터페�스를 사용하는
+사람� 한명� 없다면 그것� 삭제�다. �것� 커�� 가능한한 가장 작게
+유지�며 존재하는 모든 가능성� 있는 �터페�스들� 테스트�다는 것�
+보장한다(사용�지 않는 �터페�스들� 유효성 검�� 하기가 거� 불가능하다).
+
+
+무엇� 해야 하나
+---------------
+�, 여러분� 메� 커� 트리� 있지 않� 리눅스 커� 드��버를 가지고
+있다면 여러분� 즉, 개발�는 무엇� 해야 하나? 모든 배��마다 다른
+커� 버젼� 위한 바�너리 드��버를 배�하는 것� 악몽�며 계�해서
+변하고 있는 커� �터페�스들� 맞처 유지보수하려고 시�하는 것� 힘든
+��다.
+
+간단하다. 여러분� 커� 드��버를 메� 커� 트리� 반�하�(우리는 여기서
+GPL� 따르는 배� 드��버� 관해 얘기하고 있다는 것� �기하�. 여러분�
+코드가 �러한 분류� 해당�지 않는다면 행운� 빈다. 여러분 스스로 어떻게든

+	Namespaces compatibility list
+
+This document contains the information about the problems user
+may have when creating tasks living in different namespaces.
+
+Here's the summary. This matrix shows the known problems, that
+occur when tasks share some namespace (the columns) while living
+in different other namespaces (the rows):
+
+	UTS	IPC	VFS	PID	User	Net
+UTS	 X
+IPC		 X	 1
+VFS			 X
+PID		 1	 1	 X
+User		 2	 2		 X
+Net						 X
+
+1. Both the IPC and the PID namespaces provide IDs to address
+   object inside the kernel. E.g. semaphore with IPCID or
+   process group with pid.
+
+   In both cases, tasks shouldn't try exposing this ID to some
+   other task living in a different namespace via a shared filesystem
+   or IPC shmem/message. The fact is that this ID is only valid
+   within the namespace it was obtained in and may refer to some
+   other object in another namespace.
+
+2. Intentionally, two equal user IDs in different user namespaces
+   should not be equal from the VFS point of view. In other
+   words, user 10 in one user namespace shouldn't have the same
+   access permissions to files, belonging to user 10 in another
+   namespace.
+
+   The same is true for the IPC namespaces being shared - two users
+   from different user namespaces should not access the same IPC objects
+   even having equal UIDs.
+
+   But currently this is not so.

-		COMX drivers for the 2.2 kernel
-
-Originally written by: Tivadar Szemethy, <tiv@itc.hu>
-Currently maintained by: Gergely Madarasz <gorgo@itc.hu>
-
-Last change: 21/06/1999.
-
-INTRODUCTION
-
-This document describes the software drivers and their use for the 
-COMX line of synchronous serial adapters for Linux version 2.2.0 and
-above.
-The cards are produced and sold by ITC-Pro Ltd. Budapest, Hungary
-For further info contact <info@itc.hu> 
-or http://www.itc.hu (mostly in Hungarian).
-The firmware files and software are available from ftp://ftp.itc.hu
-
-Currently, the drivers support the following cards and protocols:
-
-COMX (2x64 kbps intelligent board)
-CMX (1x256 + 1x128 kbps intelligent board)
-HiCOMX (2x2Mbps intelligent board)
-LoCOMX (1x512 kbps passive board)
-MixCOM (1x512 or 2x512kbps passive board with a hardware watchdog an
-	optional BRI interface and optional flashROM (1-32M))
-SliceCOM	(1x2Mbps channelized E1 board)
-PciCOM	(X21)
-
-At the moment of writing this document, the (Cisco)-HDLC, LAPB, SyncPPP and
-Frame Relay (DTE, rfc1294 IP encapsulation with partially implemented Q933a 
-LMI) protocols are available as link-level protocol. 
-X.25 support is being worked on.
-
-USAGE
-
-Load the comx.o module and the hardware-specific and protocol-specific 
-modules you'll need into the running kernel using the insmod utility.
-This creates the /proc/comx directory.
-See the example scripts in the 'etc' directory.
-
-/proc INTERFACE INTRO
-
-The COMX driver set has a new type of user interface based on the /proc 
-filesystem which eliminates the need for external user-land software doing 
-IOCTL calls. 
-Each network interface or device (i.e. those ones you configure with 'ifconfig'
-and 'route' etc.) has a corresponding directory under /proc/comx. You can
-dynamically create a new interface by saying 'mkdir /proc/comx/comx0' (or you
-can name it whatever you want up to 8 characters long, comx[n] is just a 
-convention).
-Generally the files contained in these directories are text files, which can
-be viewed by 'cat filename' and you can write a string to such a file by
-saying 'echo _string_ >filename'. This is very similar to the sysctl interface.
-Don't use a text editor to edit these files, always use 'echo' (or 'cat'
-where appropriate).
-When you've created the comx[n] directory, two files are created automagically
-in it: 'boardtype' and 'protocol'. You have to fill in these files correctly
-for your board and protocol you intend to use (see the board and protocol 
-descriptions in this file below or the example scripts in the 'etc' directory).
-After filling in these files, other files will appear in the directory for 
-setting the various hardware- and protocol-related informations (for example
-irq and io addresses, keepalive values etc.) These files are set to default 
-values upon creation, so you don't necessarily have to change all of them.
-
-When you're ready with filling in the files in the comx[n] directory, you can
-configure the corresponding network interface with the standard network 
-configuration utilities. If you're unable to bring the interfaces up, look up
-the various kernel log files on your system, and consult the messages for
-a probable reason.
-
-EXAMPLE
-
-To create the interface 'comx0' which is the first channel of a COMX card:
-
-insmod comx 
-# insmod comx-hw-comx ; insmod comx-proto-ppp  (these are usually
-autoloaded if you use the kernel module loader)
-
-mkdir /proc/comx/comx0
-echo comx >/proc/comx/comx0/boardtype
-echo 0x360 >/proc/comx/comx0/io		<- jumper-selectable I/O port 
-echo 0x0a >/proc/comx/comx0/irq		<- jumper-selectable IRQ line
-echo 0xd000 >/proc/comx/comx0/memaddr	<- software-configurable memory
-					   address. COMX uses 64 KB, and this
-					   can be: 0xa000, 0xb000, 0xc000, 
-					   0xd000, 0xe000. Avoid conflicts
-					   with other hardware.
-cat </etc/siol1.rom >/proc/comx/comx0/firmware <- the firmware for the card
-echo HDLC >/proc/comx/comx0/protocol	<- the data-link protocol
-echo 10 >/proc/comx/comx0/keepalive	<- the keepalive for the protocol
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255 <-
-					   finally configure it with ifconfig
-Check its status:
-cat /proc/comx/comx0/status
-
-If you want to use the second channel of this board:
-
-mkdir /proc/comx/comx1
-echo comx >/proc/comx/comx1/boardtype
-echo 0x360 >/proc/comx/comx1/io	
-echo 10 >/proc/comx/comx1/irq		
-echo 0xd000 >/proc/comx/comx1/memaddr
-echo 1 >/proc/comx/comx1/channel	<- channels are numbered 
-					   as 0 (default) and 1
-
-Now, check if the driver recognized that you're going to use the other
-channel of the same adapter:
-
-cat /proc/comx/comx0/twin
-comx1
-cat /proc/comx/comx1/twin
-comx0
-
-You don't have to load the firmware twice, if you use both channels of
-an adapter, just write it into the channel 0's /proc firmware file.
-
-Default values: io 0x360 for COMX, 0x320 (HICOMX), irq 10, memaddr 0xd0000
-
-THE LOCOMX HARDWARE DRIVER
-
-The LoCOMX driver doesn't require firmware, and it doesn't use memory either,
-but it uses DMA channels 1 and 3. You can set the clock rate (if enabled by
-jumpers on the board) by writing the kbps value into the file named 'clock'.
-Set it to 'external' (it is the default) if you have external clock source.
-
-(Note: currently the LoCOMX driver does not support the internal clock)
-
-THE COMX, CMX AND HICOMX DRIVERS
-
-On the HICOMX, COMX and CMX, you have to load the firmware (it is different for
-the three cards!). All these adapters can share the same memory
-address (we usually use 0xd0000). On the CMX you can set the internal
-clock rate (if enabled by jumpers on the small adapter boards) by writing
-the kbps value into the 'clock' file. You have to do this before initializing
-the card. If you use both HICOMX and CMX/COMX cards, initialize the HICOMX
-first. The I/O address of the HICOMX board is not configurable by any
-method available to the user: it is hardwired to 0x320, and if you have to 
-change it, consult ITC-Pro Ltd.
-
-THE MIXCOM DRIVER
-
-The MixCOM board doesn't require firmware, the driver communicates with
-it through I/O ports. You can have three of these cards in one machine.
-
-THE SLICECOM DRIVER
-
-The SliceCOM board doesn't require firmware. You can have 4 of these cards
-in one machine. The driver doesn't (yet) support shared interrupts, so
-you will need a separate IRQ line for every board.
-Read Documentation/networking/slicecom.txt for help on configuring
-this adapter.
-
-THE HDLC/PPP LINE PROTOCOL DRIVER
-
-The HDLC/SyncPPP line protocol driver uses the kernel's built-in syncppp
-driver (syncppp.o). You don't have to manually select syncppp.o when building
-the kernel, the dependencies compile it in automatically.
-
-
-
-
-EXAMPLE
-(setting up hw parameters, see above)
-
-# using HDLC:
-echo hdlc >/proc/comx/comx0/protocol
-echo 10 >/proc/comx/comx0/keepalive	<- not necessary, 10 is the default
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
-
-(setting up hw parameters, see above)
-
-# using PPP:
-echo ppp >/proc/comx/comx0/protocol
-ifconfig comx0 up
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
-
-
-THE LAPB LINE PROTOCOL DRIVER
-
-For this, you'll need to configure LAPB support (See 'LAPB Data Link Driver' in
-'Network options' section) into your kernel (thanks to Jonathan Naylor for his 
-excellent implementation). 
-comx-proto-lapb.o provides the following files in the appropriate directory
-(the default values in parens): t1 (5), t2 (1), n2 (20), mode (DTE, STD) and
-window (7). Agree with the administrator of your peer router on these
-settings (most people use defaults, but you have to know if you are DTE or
-DCE).
-
-EXAMPLE
-
-(setting up hw parameters, see above)
-echo lapb >/proc/comx/comx0/protocol
-echo dce >/proc/comx/comx0/mode		<- DCE interface in this example
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
-
-
-THE FRAME RELAY PROTOCOL DRIVER
-
-You DON'T need any other frame relay related modules from the kernel to use
-COMX-Frame Relay. This protocol is a bit more complicated than the others, 
-because it allows to use 'subinterfaces' or DLCIs within one physical device.
-First you have to create the 'master' device (the actual physical interface)
-as you would do for other protocols. Specify 'frad' as protocol type.
-Now you can bring this interface up by saying 'ifconfig comx0 up' (or whatever
-you've named the interface). Do not assign any IP address to this interface
-and do not set any routes through it.
-Then, set up your DLCIs the following way: create a comx interface for each
-DLCI you intend to use (with mkdir), and write 'dlci' to the 'boardtype' file, 
-and 'ietf-ip' to the 'protocol' file. Currently, the only supported 
-encapsulation type is this (also called as RFC1294/1490 IP encapsulation).
-Write the DLCI number to the 'dlci' file, and write the name of the physical
-COMX device to the file called 'master'. 
-Now you can assign an IP address to this interface and set routes using it.
-See the example file for further info and example config script.
-Notes: this driver implements a DTE interface with partially implemented
-Q933a LMI.
-You can find an extensively commented example in the 'etc' directory.

-boardtype:
-Type of the hardware. Valid values are:
- 'comx', 'hicomx', 'locomx', 'cmx', 'slicecom'.
-
-protocol:
-Data-link protocol on this channel. Can be: HDLC, LAPB, PPP, FRAD
-
-status:
-You can read the channel's actual status from the 'status' file, for example
-'cat /proc/comx/comx3/status'.
-
-lineup_delay:
-Interpreted in seconds (default is 1). Used to avoid line jitter: the system
-will consider the line status 'UP' only if it is up for at least this number
-of seconds.
-
-debug: 
-You can set various debug options through this file. Valid options are:
-'comx_events', 'comx_tx', 'comx_rx', 'hw_events', 'hw_tx', 'hw_rx'.
-You can enable a debug options by writing its name prepended by a '+' into
-the debug file, for example 'echo +comx_rx >comx0/debug'. 
-Disabling an option happens similarly, use the '-' prefix 
-(e.g. 'echo -hw_rx >debug').
-Debug results can be read from the debug file, for example: 
-tail -f /proc/comx/comx2/debug

-NCSA telnet doesn't work with path MTU discovery enabled. This is due to a

-such as Solaris.

-There is a fixed version somewhere on ftp.upe.ac.za (sorry, I don't

-It may or may not be faster for you to get it from
-ftp://ftp.ists.pwr.wroc.pl/pub/msdos/telnet/ncsa_upe/tel23074.zip
-(source is in v230704s.zip).  I have tested it with 1.3.79 (with
-path mtu discovery enabled - ncsa 2.3.08 didn't work) and it seems
-to work.  I don't know if anyone is working on this code - this
-version is over a year old.  Too bad - it's faster and often more
-stable than these windoze telnets, and runs on almost anything...

-This is the README for the Gracilis Packetwin device driver, version 0.5
-ALPHA for Linux 1.3.43.
-
-These files will allow you to talk to the PackeTwin (now know as PT) and
-connect through it just like a pair of TNCs.  To do this you will also
-require the AX.25 code in the kernel enabled.
-
-There are four files in this archive; this readme, a patch file, a .c file
-and finally a .h file.  The two program files need to be put into the
-drivers/net directory in the Linux source tree, for me this is the
-directory /usr/src/linux/drivers/net.  The patch file needs to be patched in
-at the top of the Linux source tree (/usr/src/linux in my case).
-
-You will most probably have to edit the pt.c file to suit your own setup,
-this should just involve changing some of the defines at the top of the file. 
-Please note that if you run an external modem you must specify a speed of 0.
-
-The program is currently setup to run a 4800 baud external modem on port A
-and a Kantronics DE-9600 daughter board on port B so if you have this (or
-something similar) then you're right.
-
-To compile in the driver, put the files in the correct place and patch in
-the diff.  You will have to re-configure the kernel again before you
-recompile it. 
-
-The driver is not real good at the moment for finding the card.  You can
-'help' it by changing the order of the potential addresses in the structure
-found in the pt_init() function so the address of where the card is is put
-first.
-
-After compiling, you have to get them going, they are pretty well like any
-other net device and just need ifconfig to get them going.
-As an example, here is my /etc/rc.net
---------------------------

-
-This version of the driver comes under the GNU GPL.  If you have one of my
-previous (non-GPL) versions of the driver, please update to this one.
-
-I hope that this all works well for you.  I would be pleased to hear how
-many people use the driver and if it does its job.

-Usage:
-
-Compiling the kernel:
-
-Code maturity level options
-	[*] Prompt for development and/or incomplete code/drivers
-
-Network device support
-	Wan interfaces
-		<M> MultiGate (COMX) synchronous
-			<M> Support for MUNICH based boards: SliceCOM, PCICOM (NEW)
-			<M> Support for HDLC and syncPPP...
-
-
-Loading the modules:
-
-modprobe comx
-
-modprobe comx-proto-ppp		# module for  Cisco-HDLC and SyncPPP protocols
-
-modprobe comx-hw-munich		# the module logs information by the kernel
-				# about the detected boards
-
-
-Configuring the board:
-
-# This interface will use the Cisco-HDLC line protocol,
-# the timeslices assigned are 1,2 (128 KiBit line speed)
-# (the first data timeslice in the G.703 frame is no. 1)
-#
-mkdir /proc/comx/comx0.1/
-echo slicecom	>/proc/comx/comx0.1/boardtype
-echo hdlc	>/proc/comx/comx0.1/protocol
-echo 1 2	>/proc/comx/comx0.1/timeslots
-
-
-# This interface uses SyncPPP line protocol, the assigned

-#
-mkdir /proc/comx/comx0.2/
-echo slicecom	>/proc/comx/comx0.2/boardtype
-echo ppp	>/proc/comx/comx0.2/protocol
-echo 3		>/proc/comx/comx0.2/timeslots
-
-...
-
-ifconfig comx0.1 up
-ifconfig comx0.2 up
-
------------------------------------------------------------------
-
-The COMX interfaces use a 10 packet transmit queue by default, however WAN
-networks sometimes use bigger values (20 to 100), to utilize the line better
-by large traffic (though the line delay increases because of more packets
-join the queue).
-
-# ifconfig comx0 txqueuelen 50
-
-This option is only supported by the ifconfig command of the later 
-distributions, which came with 2.2 kernels, such as RedHat 6.1 or Debian 2.2.
-
-You can download a newer netbase packet from 
-http://www.debian.org/~rcw/2.2/netbase/ for Debian 2.1, which has a new
-ifconfig. You can get further information about using 2.2 kernel with
-Debian 2.1 from http://www.debian.org/releases/stable/running-kernel-2.2
-
------------------------------------------------------------------
-
-The SliceCom LEDs:
-
-red	- on, if the interface is unconfigured, or it gets Remote Alarm-s
-green	- on, if the board finds frame-sync in the received signal 	
-
-A bit more detailed:
-
-red:	green:	meaning:
-
--	-	no frame-sync, no signal received, or signal SNAFU.
--	on	"Everything is OK"
-on	on	Reception is ok, but the remote end sends Remote Alarm
-on	-	The interface is unconfigured
-
------------------------------------------------------------------
-
-A more detailed description of the hardware setting options:
-
-The general and the protocol layer options described in the 'comx.txt' file
-apply to the SliceCom as well, I only summarize the SliceCom hardware specific
-settings below.
-
-The '/proc/comx' configuring interface:
-
-An interface directory should be created for every timeslot group with
-'mkdir', e,g: 'comx0', 'comx1' etc. The timeslots can be assigned here to the
-specific interface. The Cisco-like naming convention (serial3:1 - first
-timeslot group of the 3rd. board) can't be used here, because these mean IP
-aliasing in Linux.
-
-You can give any meaningful name to keep the configuration clear; 
-e.g: 'comx0.1', 'comx0.2', 'comx1.1', comx1.2', if you have two boards
-with two interfaces each.
-
-Settings, which apply to the board:
-
-Neither 'io' nor 'irq' settings required, the driver uses the resources
-given by the PCI BIOS.
-
-comx0/boardnum	- board number of the SliceCom in the PC (using the 'natural'
-		PCI order) as listed in '/proc/pci' or the output of the
-	 	'lspci' command, generally the slots nearer to the motherboard
-		PCI driver chips have the lower numbers.
-		
-		Default: 0 (the counting starts with 0)
-
-Though the options below are to be set on a single interface, they apply to the
-whole board. The restriction, to use them on 'UP' interfaces, is because the 
-command sequence below could lead to unpredictable results.
-
-	# echo 0        >boardnum
-	# echo internal >clock_source
-	# echo 1        >boardnum
-
-The sequence would set the clock source of board 0.
-
-These settings will persist after all the interfaces are cleared, but are
-cleared when the driver module is unloaded and loaded again.
-
-comx0/clock_source - source of the transmit clock
-	Usage:
-
-	# echo line     >/proc/comx/comx0/clock_source
-	# echo internal >/proc/comx/comx0/clock_source
-
-	line	- The Tx clock is being decoded if the input data stream,
-		if no clock seen on the input, then the board will use it's
-		own clock generator.
-
-	internal - The Tx clock is supplied by the builtin clock generator. 	
-
-	Default: line
-
-	Normally, the telecommunication company's end device (the HDSL
-	modem) provides the Tx clock, that's why 'line' is the default.
-
-comx0/framing	- Switching CRC4 off/on
-
-	CRC4: 16 PCM frames (The 32 64Kibit channels are multiplexed into a
-	PCM frame, nothing to do with HDLC frames) are divided into 2x8
-	groups, each group has a 4 bit CRC.
-
-	# echo crc4	>/proc/comx/comx0/framing
-	# echo no-crc4	>/proc/comx/comx0/framing
-
-	Default is 'crc4', the Hungarian MATAV lines behave like this. 
-	The traffic generally passes if this setting on both ends don't match.
-
-comx0/linecode	- Setting the line coding
-
-	# echo hdb3	>/proc/comx/comx0/linecode
-	# echo ami	>/proc/comx/comx0/linecode
-
-	Default a 'hdb3', MATAV lines use this.
-	
-	(AMI coding is rarely used with E1 lines). Frame sync may occur, if
-	this setting doesn't match the other end's, but CRC4 and data errors
-	will come, which will result in CRC errors on HDLC/SyncPPP level. 
-
-comx0/reg	- direct access to the board's MUNICH (reg) and FALC (lbireg)
-comx0/lbireg	circuit's registers  
-
-	# echo >reg 0x04 0x0	- write 0 to register 4
-	# echo >reg 0x104	- write the contents of register 4 with
-				printk() to syslog
-
-WARNING! These are only for development purposes, messing with this will
-	result much trouble!
-
-comx0/loopback - Places a loop to the board's G.703 signals
-
-	# echo none   >/proc/comx/comx0/loopback
-	# echo local  >/proc/comx/comx0/loopback
-	# echo remote >/proc/comx/comx0/loopback
-
-	none   - normal operation, no loop
-	local  - the board receives it's own output
-	remote - the board sends the received data to the remote side
-
-	Default: none
-
------------------------------------------------------------------
-
-Interface (channel group in Cisco terms) settings: 
-
-comx0/timeslots	- which timeslots belong to the given interface
-
-	Setting:
-
-	# echo '1 5 2 6 7 8' >/proc/comx/comx0/timeslots
-
-	# cat /proc/comx/comx0/timeslots
-	1 2 5 6 7 8 
-	#
-
-	Finding a timeslot: 
-
-	# grep ' 4' /proc/comx/comx*/timeslots
-	/proc/comx/comx0/timeslots:1 3 4 5 6
-	#
-
-	The timeslots can be in any order, '1 2 3' is the same as '1 3 2'.
-
-	The interface has to be DOWN during the setting ('ifconfig comx0
-	down'), but the other interfaces could operate normally.
-
-	The driver checks if the assigned timeslots are vacant, if not, then
-	the setting won't be applied.
-
-	The timeslot values are treated as decimal numbers, not to misunderstand
-	values of 08, 09 form.

+   l) Xilinx IP cores
+
+   The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
+   in Xilinx Spartan and Virtex FPGAs.  The devices cover the whole range
+   of standard device types (network, serial, etc.) and miscellanious
+   devices (gpio, LCD, spi, etc).  Also, since these devices are
+   implemented within the fpga fabric every instance of the device can be
+   synthesised with different options that change the behaviour.
+
+   Each IP-core has a set of parameters which the FPGA designer can use to
+   control how the core is synthesized.  Historically, the EDK tool would
+   extract the device parameters relevant to device drivers and copy them
+   into an 'xparameters.h' in the form of #define symbols.  This tells the
+   device drivers how the IP cores are configured, but it requres the kernel
+   to be recompiled every time the FPGA bitstream is resynthesized.
+
+   The new approach is to export the parameters into the device tree and
+   generate a new device tree each time the FPGA bitstream changes.  The
+   parameters which used to be exported as #defines will now become
+   properties of the device node.  In general, device nodes for IP-cores
+   will take the following form:
+
+	(name)@(base-address) {
+		compatible = "xlnx,(ip-core-name)-(HW_VER)"
+			     [, (list of compatible devices), ...];
+		reg = <(baseaddr) (size)>;
+		interrupt-parent = <&interrupt-controller-phandle>;
+		interrupts = < ... >;
+		xlnx,(parameter1) = "(string-value)";
+		xlnx,(parameter2) = <(int-value)>;
+	};
+
+	(ip-core-name):	the name of the ip block (given after the BEGIN
+			directive in system.mhs).  Should be in lowercase
+			and all underscores '_' converted to dashes '-'.
+	(name):		is derived from the "PARAMETER INSTANCE" value.
+	(parameter#):	C_* parameters from system.mhs.  The C_ prefix is
+			dropped from the parameter name, the name is converted
+			to lowercase and all underscore '_' characters are
+			converted to dashes '-'.
+	(baseaddr):	the C_BASEADDR parameter.
+	(HW_VER):	from the HW_VER parameter.
+	(size):		equals C_HIGHADDR - C_BASEADDR + 1
+
+   Typically, the compatible list will include the exact IP core version
+   followed by an older IP core version which implements the same
+   interface or any other device with the same interface.
+
+   'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
+
+   For example, the following block from system.mhs:
+
+	BEGIN opb_uartlite
+		PARAMETER INSTANCE = opb_uartlite_0
+		PARAMETER HW_VER = 1.00.b
+		PARAMETER C_BAUDRATE = 115200
+		PARAMETER C_DATA_BITS = 8
+		PARAMETER C_ODD_PARITY = 0
+		PARAMETER C_USE_PARITY = 0
+		PARAMETER C_CLK_FREQ = 50000000
+		PARAMETER C_BASEADDR = 0xEC100000
+		PARAMETER C_HIGHADDR = 0xEC10FFFF
+		BUS_INTERFACE SOPB = opb_7
+		PORT OPB_Clk = CLK_50MHz
+		PORT Interrupt = opb_uartlite_0_Interrupt
+		PORT RX = opb_uartlite_0_RX
+		PORT TX = opb_uartlite_0_TX
+		PORT OPB_Rst = sys_bus_reset_0
+	END
+
+   becomes the following device tree node:
+
+	opb-uartlite-0@ec100000 {
+		device_type = "serial";
+		compatible = "xlnx,opb-uartlite-1.00.b";
+		reg = <ec100000 10000>;
+		interrupt-parent = <&opb-intc>;
+		interrupts = <1 0>; // got this from the opb_intc parameters
+		current-speed = <d#115200>;	// standard serial device prop
+		clock-frequency = <d#50000000>;	// standard serial device prop
+		xlnx,data-bits = <8>;
+		xlnx,odd-parity = <0>;
+		xlnx,use-parity = <0>;
+	};
+
+   Some IP cores actually implement 2 or more logical devices.  In this case,
+   the device should still describe the whole IP core with a single node
+   and add a child node for each logical device.  The ranges property can
+   be used to translate from parent IP-core to the registers of each device.
+   (Note: this makes the assumption that both logical devices have the same
+   bus binding.  If this is not true, then separate nodes should be used for
+   each logical device).  The 'cell-index' property can be used to enumerate
+   logical devices within an IP core.  For example, the following is the
+   system.mhs entry for the dual ps2 controller found on the ml403 reference
+   design.
+
+	BEGIN opb_ps2_dual_ref
+		PARAMETER INSTANCE = opb_ps2_dual_ref_0
+		PARAMETER HW_VER = 1.00.a
+		PARAMETER C_BASEADDR = 0xA9000000
+		PARAMETER C_HIGHADDR = 0xA9001FFF
+		BUS_INTERFACE SOPB = opb_v20_0
+		PORT Sys_Intr1 = ps2_1_intr
+		PORT Sys_Intr2 = ps2_2_intr
+		PORT Clkin1 = ps2_clk_rx_1
+		PORT Clkin2 = ps2_clk_rx_2
+		PORT Clkpd1 = ps2_clk_tx_1
+		PORT Clkpd2 = ps2_clk_tx_2
+		PORT Rx1 = ps2_d_rx_1
+		PORT Rx2 = ps2_d_rx_2
+		PORT Txpd1 = ps2_d_tx_1
+		PORT Txpd2 = ps2_d_tx_2
+	END
+
+   It would result in the following device tree nodes:
+
+	opb_ps2_dual_ref_0@a9000000 {
+		ranges = <0 a9000000 2000>;
+		// If this device had extra parameters, then they would
+		// go here.
+		ps2@0 {
+			compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
+			reg = <0 40>;
+			interrupt-parent = <&opb-intc>;
+			interrupts = <3 0>;
+			cell-index = <0>;
+		};
+		ps2@1000 {
+			compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
+			reg = <1000 40>;
+			interrupt-parent = <&opb-intc>;
+			interrupts = <3 0>;
+			cell-index = <0>;
+		};
+	};
+
+   Also, the system.mhs file defines bus attachments from the processor
+   to the devices.  The device tree structure should reflect the bus
+   attachments.  Again an example; this system.mhs fragment:
+
+	BEGIN ppc405_virtex4
+		PARAMETER INSTANCE = ppc405_0
+		PARAMETER HW_VER = 1.01.a
+		BUS_INTERFACE DPLB = plb_v34_0
+		BUS_INTERFACE IPLB = plb_v34_0
+	END
+
+	BEGIN opb_intc
+		PARAMETER INSTANCE = opb_intc_0
+		PARAMETER HW_VER = 1.00.c
+		PARAMETER C_BASEADDR = 0xD1000FC0
+		PARAMETER C_HIGHADDR = 0xD1000FDF
+		BUS_INTERFACE SOPB = opb_v20_0
+	END
+
+	BEGIN opb_uart16550
+		PARAMETER INSTANCE = opb_uart16550_0
+		PARAMETER HW_VER = 1.00.d
+		PARAMETER C_BASEADDR = 0xa0000000
+		PARAMETER C_HIGHADDR = 0xa0001FFF
+		BUS_INTERFACE SOPB = opb_v20_0
+	END
+
+	BEGIN plb_v34
+		PARAMETER INSTANCE = plb_v34_0
+		PARAMETER HW_VER = 1.02.a
+	END
+
+	BEGIN plb_bram_if_cntlr
+		PARAMETER INSTANCE = plb_bram_if_cntlr_0
+		PARAMETER HW_VER = 1.00.b
+		PARAMETER C_BASEADDR = 0xFFFF0000
+		PARAMETER C_HIGHADDR = 0xFFFFFFFF
+		BUS_INTERFACE SPLB = plb_v34_0
+	END
+
+	BEGIN plb2opb_bridge
+		PARAMETER INSTANCE = plb2opb_bridge_0
+		PARAMETER HW_VER = 1.01.a
+		PARAMETER C_RNG0_BASEADDR = 0x20000000
+		PARAMETER C_RNG0_HIGHADDR = 0x3FFFFFFF
+		PARAMETER C_RNG1_BASEADDR = 0x60000000
+		PARAMETER C_RNG1_HIGHADDR = 0x7FFFFFFF
+		PARAMETER C_RNG2_BASEADDR = 0x80000000
+		PARAMETER C_RNG2_HIGHADDR = 0xBFFFFFFF
+		PARAMETER C_RNG3_BASEADDR = 0xC0000000
+		PARAMETER C_RNG3_HIGHADDR = 0xDFFFFFFF
+		BUS_INTERFACE SPLB = plb_v34_0
+		BUS_INTERFACE MOPB = opb_v20_0
+	END
+
+   Gives this device tree (some properties removed for clarity):
+
+	plb-v34-0 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		device_type = "ibm,plb";
+		ranges; // 1:1 translation
+
+		plb-bram-if-cntrl-0@ffff0000 {
+			reg = <ffff0000 10000>;
+		}
+
+		opb-v20-0 {
+			#address-cells = <1>;
+			#size-cells = <1>;
+			ranges = <20000000 20000000 20000000
+				  60000000 60000000 20000000

+
+			opb-intc-0@d1000fc0 {

+			};
+		};
+	};
+
+   That covers the general approach to binding xilinx IP cores into the
+   device tree.  The following are bindings for specific devices:
+
+      i) Xilinx ML300 Framebuffer
+
+      Simple framebuffer device from the ML300 reference design (also on the
+      ML403 reference design as well as others).
+
+      Optional properties:
+       - resolution = <xres yres> : pixel resolution of framebuffer.  Some
+                                    implementations use a different resolution.
+                                    Default is <d#640 d#480>
+       - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
+                                           Default is <d#1024 d#480>.
+       - rotate-display (empty) : rotate display 180 degrees.
+
+      ii) Xilinx SystemACE
+
+      The Xilinx SystemACE device is used to program FPGAs from an FPGA
+      bitstream stored on a CF card.  It can also be used as a generic CF
+      interface device.
+
+      Optional properties:
+       - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
+
+      iii) Xilinx EMAC and Xilinx TEMAC
+
+      Xilinx Ethernet devices.  In addition to general xilinx properties
+      listed above, nodes for these devices should include a phy-handle
+      property, and may include other common network device properties
+      like local-mac-address.
+      
+      iv) Xilinx Uartlite
+
+      Xilinx uartlite devices are simple fixed speed serial ports.
+
+      Requred properties:
+       - current-speed : Baud rate of uartlite
+
    More devices will be defined as this spec matures.

-		Parallel link cable for Texas Instruments handhelds
-		===================================================
-
-
-Author: Romain Lievin
-Homepage: http://lpg.ticalc.org/prj_tidev/index.html
-
-
-INTRODUCTION:
-
-This is a driver for the very common home-made parallel link cable, a cable 
-designed for connecting TI8x/9x graphing calculators (handhelds) to a computer
-or workstation (Alpha, Sparc). Given that driver is built on parport, the 
-parallel port abstraction layer, this driver is architecture-independent.
-
-It can also be used with another device plugged on the same port (such as a
-ZIP drive). I have a 100MB ZIP and both of them work fine!
-
-If you need more information, please visit the 'TI drivers' homepage at the URL
-above.
-
-WHAT YOU NEED:
-
-A TI calculator and a program capable of communicating with your calculator.
-
-TiLP will work for sure (since I am its developer!). yal92 may be able to use
-it by changing tidev for tipar (may require some hacking...).
-
-HOW TO USE IT:
-
-You must have first compiled parport support (CONFIG_PARPORT_DEV): either 
-compiled in your kernel, either as a module. 
-
-Next, (as root):
-
-       modprobe parport
-       modprobe tipar
-
-If it is not already there (it usually is), create the device:
-
-       mknod /dev/tipar0 c 115 0
-       mknod /dev/tipar1 c 115 1
-       mknod /dev/tipar2 c 115 2
-
-You will have to set permissions on this device to allow you to read/write
-from it:
-
-       chmod 666 /dev/tipar[0..2]
-       
-Now you are ready to run a linking program such as TiLP. Be sure to configure 
-it properly (RTFM).
-       
-MODULE PARAMETERS:
-
-  You can set these with:  modprobe tipar NAME=VALUE
-  There is currently no way to set these on a per-cable basis.
-
-  NAME: timeout
-  TYPE: integer
-  DEFAULT: 15
-  DESC: Timeout value in tenth of seconds. If no data is available once this 
-	time has expired then the driver will return with a timeout error.
-
-  NAME: delay
-  TYPE: integer
-  DEFAULT: 10
-  DESC: Inter-bit delay in micro-seconds. A lower value gives an higher data
-	rate but makes transmission less reliable.
-
-These parameters can be changed at run time by any program via ioctl(2) calls 
-as listed in ./include/linux/ticable.h.
-
-Rather than write 50 pages describing the ioctl() and so on, it is
-perhaps more useful you look at ticables library (dev_link.c) that demonstrates
-how to use them, and demonstrates the features of the driver. This is
-probably a lot more useful to people interested in writing applications
-that will be using this driver.
-
-QUIRKS/BUGS:
-
-None.
-
-HOW TO CONTACT US:
-
-You can email me at roms@lpg.ticalc.org. Please prefix the subject line
-with "TIPAR: " so that I am certain to notice your message.
-You can also mail JB at jb@jblache.org. He packaged these drivers for Debian.
-
-CREDITS:
-
-The code is based on tidev.c & parport.c.
-The driver has been developed independently of Texas Instruments.

+General note on [U]EFI x86_64 support
+-------------------------------------
+
+The nomenclature EFI and UEFI are used interchangeably in this document.
+
+Although the tools below are _not_ needed for building the kernel,
+the needed bootloader support and associated tools for x86_64 platforms
+with EFI firmware and specifications are listed below.
+
+1. UEFI specification:  http://www.uefi.org
+
+2. Booting Linux kernel on UEFI x86_64 platform requires bootloader
+   support. Elilo with x86_64 support can be used.
+
+3. x86_64 platform with EFI/UEFI firmware.
+
+Mechanics:
+---------
+- Build the kernel with the following configuration.
+	CONFIG_FB_EFI=y
+	CONFIG_FRAMEBUFFER_CONSOLE=y
+- Create a VFAT partition on the disk
+- Copy the following to the VFAT partition:
+	elilo bootloader with x86_64 support, elilo configuration file,
+	kernel image built in first step and corresponding
+	initrd. Instructions on building elilo	and its dependencies
+	can be found in the elilo sourceforge project.
+- Boot to EFI shell and invoke elilo choosing the kernel image built
+  in first step.

  * Fast timers for ETRAX100/ETRAX100LX
- * This may be useful in other OS than Linux so use 2 space indentation...
  *
- * $Log: fasttimer.c,v $
- * Revision 1.9  2005/03/04 08:16:16  starvik
- * Merge of Linux 2.6.11.
- *
- * Revision 1.8  2005/01/05 06:09:29  starvik
- * cli()/sti() will be obsolete in 2.6.11.
- *
- * Revision 1.7  2005/01/03 13:35:46  starvik
- * Removed obsolete stuff.
- * Mark fast timer IRQ as not shared.
- *
- * Revision 1.6  2004/05/14 10:18:39  starvik
- * Export fast_timer_list
- *
- * Revision 1.5  2004/05/14 07:58:01  starvik
- * Merge of changes from 2.4
- *
- * Revision 1.4  2003/07/04 08:27:41  starvik
- * Merge of Linux 2.5.74
- *
- * Revision 1.3  2002/12/12 08:26:32  starvik
- * Don't use C-comments inside CVS comments
- *
- * Revision 1.2  2002/12/11 15:42:02  starvik
- * Extracted v10 (ETRAX 100LX) specific stuff from arch/cris/kernel/
- *
- * Revision 1.1  2002/11/18 07:58:06  starvik
- * Fast timers (from Linux 2.4)
- *
- * Revision 1.5  2002/10/15 06:21:39  starvik
- * Added call to init_waitqueue_head
- *
- * Revision 1.4  2002/05/28 17:47:59  johana
- * Added del_fast_timer()
- *
- * Revision 1.3  2002/05/28 16:16:07  johana
- * Handle empty fast_timer_list
- *
- * Revision 1.2  2002/05/27 15:38:42  johana
- * Made it compile without warnings on Linux 2.4.
- * (includes, wait_queue, PROC_FS and snprintf)
- *
- * Revision 1.1  2002/05/27 15:32:25  johana
- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
- *
- * Revision 1.8  2001/11/27 13:50:40  pkj
- * Disable interrupts while stopping the timer and while modifying the
- * list of active timers in timer1_handler() as it may be interrupted
- * by other interrupts (e.g., the serial interrupt) which may add fast
- * timers.
- *
- * Revision 1.7  2001/11/22 11:50:32  pkj
- * * Only store information about the last 16 timers.
- * * proc_fasttimer_read() now uses an allocated buffer, since it
- *   requires more space than just a page even for only writing the
- *   last 16 timers. The buffer is only allocated on request, so
- *   unless /proc/fasttimer is read, it is never allocated.
- * * Renamed fast_timer_started to fast_timers_started to match
- *   fast_timers_added and fast_timers_expired.
- * * Some clean-up.
- *
- * Revision 1.6  2000/12/13 14:02:08  johana
- * Removed volatile for fast_timer_list
- *
- * Revision 1.5  2000/12/13 13:55:35  johana
- * Added DEBUG_LOG, added som cli() and cleanup
- *
- * Revision 1.4  2000/12/05 13:48:50  johana
- * Added range check when writing proc file, modified timer int handling
- *
- * Revision 1.3  2000/11/23 10:10:20  johana
- * More debug/logging possibilities.
- * Moved GET_JIFFIES_USEC() to timex.h and time.c
- *
- * Revision 1.2  2000/11/01 13:41:04  johana
- * Clean up and bugfixes.
- * Created new do_gettimeofday_fast() that gets a timeval struct
- * with time based on jiffies and *R_TIMER0_DATA, uses a table
- * for fast conversion of timer value to microseconds.
- * (Much faster the standard do_gettimeofday() and we don't really
- * want to use the true time - we want the "uptime" so timers don't screw up
- * when we change the time.
- * TODO: Add efficient support for continuous timers as well.
- *
- * Revision 1.1  2000/10/26 15:49:16  johana
- * Added fasttimer, highresolution timers.

-/* ROUTINES:	$$divI, $$divoI
-
-   Single precision divide for signed binary integers.
-
-   The quotient is truncated towards zero.
-   The sign of the quotient is the XOR of the signs of the dividend and
-   divisor.
-   Divide by zero is trapped.
-   Divide of -2**31 by -1 is trapped for $$divoI but not for $$divI.
-
-   INPUT REGISTERS:
-   .	arg0 ==	dividend
-   .	arg1 ==	divisor
-   .	mrp  == return pc
-   .	sr0  == return space when called externally
-
-   OUTPUT REGISTERS:
-   .	arg0 =	undefined
-   .	arg1 =	undefined
-   .	ret1 =	quotient
-
-   OTHER REGISTERS AFFECTED:
-   .	r1   =	undefined
-
-   SIDE EFFECTS:
-   .	Causes a trap under the following conditions:
-   .		divisor is zero  (traps with ADDIT,=  0,25,0)
-   .		dividend==-2**31  and divisor==-1 and routine is $$divoI
-   .				 (traps with ADDO  26,25,0)
-   .	Changes memory at the following places:
-   .		NONE
-
-   PERMISSIBLE CONTEXT:
-   .	Unwindable.
-   .	Suitable for internal or external millicode.
-   .	Assumes the special millicode register conventions.
-
-   DISCUSSION:
-   .	Branchs to other millicode routines using BE
-   .		$$div_# for # being 2,3,4,5,6,7,8,9,10,12,14,15
-   .
-   .	For selected divisors, calls a divide by constant routine written by
-   .	Karl Pettis.  Eligible divisors are 1..15 excluding 11 and 13.
-   .
-   .	The only overflow case is -2**31 divided by -1.
-   .	Both routines return -2**31 but only $$divoI traps.  */

-
-   We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
-   (with y fixed).
-
-   Let a = floor(z/y), for some choice of z.  Note that z will be
-   chosen so that division by z is cheap.
-
-   Let r be the remainder(z/y).  In other words, r = z - ay.
-
-   Now, our method is to choose a value for b such that
-
-   q'(x) = floor((ax+b)/z)
-
-   is equal to q(x) over as large a range of x as possible.  If the
-   two are equal over a sufficiently large range, and if it is easy to
-   form the product (ax), and it is easy to divide by z, then we can
-   perform the division much faster than the general division algorithm.
-
-   So, we want the following to be true:
-
-   .	For x in the following range:
-   .
-   .	    ky <= x < (k+1)y
-   .
-   .	implies that
-   .
-   .	    k <= (ax+b)/z < (k+1)
-
-   We want to determine b such that this is true for all k in the
-   range {0..K} for some maximum K.
-
-   Since (ax+b) is an increasing function of x, we can take each
-   bound separately to determine the "best" value for b.
-
-   (ax+b)/z < (k+1)	       implies
-
-   (a((k+1)y-1)+b < (k+1)z     implies
-
-   b < a + (k+1)(z-ay)	       implies
-
-   b < a + (k+1)r
-
-   This needs to be true for all k in the range {0..K}.  In
-   particular, it is true for k = 0 and this leads to a maximum
-   acceptable value for b.
-
-   b < a+r   or   b <= a+r-1
-
-   Taking the other bound, we have
-
-   k <= (ax+b)/z	       implies
-
-   k <= (aky+b)/z	       implies
-
-   k(z-ay) <= b		       implies
-
-   kr <= b
-
-   Clearly, the largest range for k will be achieved by maximizing b,
-   when r is not zero.	When r is zero, then the simplest choice for b
-   is 0.  When r is not 0, set
-
-   .	b = a+r-1
-
-   Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
-   for all x in the range:
-
-   .	0 <= x < (K+1)y
-
-   We need to determine what K is.  Of our two bounds,
-
-   .	b < a+(k+1)r	is satisfied for all k >= 0, by construction.
-
-   The other bound is
-
-   .	kr <= b
-
-   This is always true if r = 0.  If r is not 0 (the usual case), then
-   K = floor((a+r-1)/r), is the maximum value for k.
-
-   Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
-   answer for q(x) = floor(x/y) when x is in the range
-
-   (0,(K+1)y-1)	       K = floor((a+r-1)/r)
-
-   To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
-   the formula for q'(x) yields the correct value of q(x) for all x
-   representable by a single word in HPPA.
-
-   We are also constrained in that computing the product (ax), adding
-   b, and dividing by z must all be done quickly, otherwise we will be
-   better off going through the general algorithm using the DS
-   instruction, which uses approximately 70 cycles.
-
-   For each y, there is a choice of z which satisfies the constraints
-   for (K+1)y >= 2**32.  We may not, however, be able to satisfy the
-   timing constraints for arbitrary y.	It seems that z being equal to
-   a power of 2 or a power of 2 minus 1 is as good as we can do, since
-   it minimizes the time to do division by z.  We want the choice of z
-   to also result in a value for (a) that minimizes the computation of
-   the product (ax).  This is best achieved if (a) has a regular bit
-   pattern (so the multiplication can be done with shifts and adds).
-   The value of (a) also needs to be less than 2**32 so the product is
-   always guaranteed to fit in 2 words.
-
-   In actual practice, the following should be done:
-
-   1) For negative x, you should take the absolute value and remember
-   .  the fact so that the result can be negated.  This obviously does
-   .  not apply in the unsigned case.
-   2) For even y, you should factor out the power of 2 that divides y
-   .  and divide x by it.  You can then proceed by dividing by the
-   .  odd factor of y.
-
-   Here is a table of some odd values of y, and corresponding choices
-   for z which are "good".
-
-    y	  z	  r	 a (hex)     max x (hex)
-
-    3	2**32	  1	55555555      100000001
-    5	2**32	  1	33333333      100000003
-    7  2**24-1	  0	  249249     (infinite)
-    9  2**24-1	  0	  1c71c7     (infinite)
-   11  2**20-1	  0	   1745d     (infinite)
-   13  2**24-1	  0	  13b13b     (infinite)
-   15	2**32	  1	11111111      10000000d
-   17	2**32	  1	 f0f0f0f      10000000f
-
-   If r is 1, then b = a+r-1 = a.  This simplifies the computation
-   of (ax+b), since you can compute (x+1)(a) instead.  If r is 0,
-   then b = 0 is ok to use which simplifies (ax+b).
-
-   The bit patterns for 55555555, 33333333, and 11111111 are obviously
-   very regular.  The bit patterns for the other values of a above are:
-
-    y	   (hex)	  (binary)
-
-    7	  249249  001001001001001001001001  << regular >>
-    9	  1c71c7  000111000111000111000111  << regular >>
-   11	   1745d  000000010111010001011101  << irregular >>
-   13	  13b13b  000100111011000100111011  << irregular >>
-
-   The bit patterns for (a) corresponding to (y) of 11 and 13 may be
-   too irregular to warrant using this method.
-
-   When z is a power of 2 minus 1, then the division by z is slightly
-   more complicated, involving an iterative solution.
-
-   The code presented here solves division by 1 through 17, except for
-   11 and 13. There are algorithms for both signed and unsigned
-   quantities given.
-

-   .  17       16	  18	    16
-
-   Now, the algorithm for 7, 9, and 14 is an iterative one.  That is,
-   a loop body is executed until the tentative quotient is 0.  The
-   number of times the loop body is executed varies depending on the
-   dividend, but is never more than two times.	If the dividend is
-   less than the divisor, then the loop body is not executed at all.
-   Each iteration adds 4 cycles to the timings.

-
-   Single precision divide for signed binary integers.
-
-   The quotient is truncated towards zero.
-   The sign of the quotient is the XOR of the signs of the dividend and
-   divisor.
-   Divide by zero is trapped.
-   Divide of -2**31 by -1 is trapped for $$divoI but not for $$divI.
-
-   INPUT REGISTERS:
-   .	arg0 ==	dividend
-   .	arg1 ==	divisor
-   .	mrp  == return pc
-   .	sr0  == return space when called externally
-
-   OUTPUT REGISTERS:
-   .	arg0 =	undefined
-   .	arg1 =	undefined
-   .	ret1 =	quotient
-
-   OTHER REGISTERS AFFECTED:
-   .	r1   =	undefined
-
-   SIDE EFFECTS:
-   .	Causes a trap under the following conditions:
-   .		divisor is zero  (traps with ADDIT,=  0,25,0)
-   .		dividend==-2**31  and divisor==-1 and routine is $$divoI
-   .				 (traps with ADDO  26,25,0)
-   .	Changes memory at the following places:
-   .		NONE
-
-   PERMISSIBLE CONTEXT:
-   .	Unwindable.
-   .	Suitable for internal or external millicode.
-   .	Assumes the special millicode register conventions.
-
-   DISCUSSION:
-   .	Branchs to other millicode routines using BE
-   .		$$div_# for # being 2,3,4,5,6,7,8,9,10,12,14,15
-   .
-   .	For selected divisors, calls a divide by constant routine written by
-   .	Karl Pettis.  Eligible divisors are 1..15 excluding 11 and 13.
-   .
-   .	The only overflow case is -2**31 divided by -1.
-   .	Both routines return -2**31 but only $$divoI traps.  */

-/* TRUNCATED DIVISION BY SMALL INTEGERS
-
-   We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
-   (with y fixed).
-
-   Let a = floor(z/y), for some choice of z.  Note that z will be
-   chosen so that division by z is cheap.
-
-   Let r be the remainder(z/y).  In other words, r = z - ay.
-
-   Now, our method is to choose a value for b such that
-
-   q'(x) = floor((ax+b)/z)
-
-   is equal to q(x) over as large a range of x as possible.  If the
-   two are equal over a sufficiently large range, and if it is easy to
-   form the product (ax), and it is easy to divide by z, then we can
-   perform the division much faster than the general division algorithm.
-
-   So, we want the following to be true:
-
-   .	For x in the following range:
-   .
-   .	    ky <= x < (k+1)y
-   .
-   .	implies that
-   .
-   .	    k <= (ax+b)/z < (k+1)
-
-   We want to determine b such that this is true for all k in the
-   range {0..K} for some maximum K.
-
-   Since (ax+b) is an increasing function of x, we can take each
-   bound separately to determine the "best" value for b.
-
-   (ax+b)/z < (k+1)	       implies
-
-   (a((k+1)y-1)+b < (k+1)z     implies
-
-   b < a + (k+1)(z-ay)	       implies
-
-   b < a + (k+1)r
-
-   This needs to be true for all k in the range {0..K}.  In
-   particular, it is true for k = 0 and this leads to a maximum
-   acceptable value for b.
-
-   b < a+r   or   b <= a+r-1
-
-   Taking the other bound, we have
-
-   k <= (ax+b)/z	       implies
-
-   k <= (aky+b)/z	       implies
-
-   k(z-ay) <= b		       implies
-
-   kr <= b
-
-   Clearly, the largest range for k will be achieved by maximizing b,
-   when r is not zero.	When r is zero, then the simplest choice for b
-   is 0.  When r is not 0, set
-
-   .	b = a+r-1
-
-   Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
-   for all x in the range:
-
-   .	0 <= x < (K+1)y
-
-   We need to determine what K is.  Of our two bounds,
-
-   .	b < a+(k+1)r	is satisfied for all k >= 0, by construction.
-
-   The other bound is
-
-   .	kr <= b
-
-   This is always true if r = 0.  If r is not 0 (the usual case), then
-   K = floor((a+r-1)/r), is the maximum value for k.
-
-   Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
-   answer for q(x) = floor(x/y) when x is in the range
-
-   (0,(K+1)y-1)	       K = floor((a+r-1)/r)
-
-   To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
-   the formula for q'(x) yields the correct value of q(x) for all x
-   representable by a single word in HPPA.
-
-   We are also constrained in that computing the product (ax), adding
-   b, and dividing by z must all be done quickly, otherwise we will be
-   better off going through the general algorithm using the DS
-   instruction, which uses approximately 70 cycles.
-
-   For each y, there is a choice of z which satisfies the constraints
-   for (K+1)y >= 2**32.  We may not, however, be able to satisfy the
-   timing constraints for arbitrary y.	It seems that z being equal to
-   a power of 2 or a power of 2 minus 1 is as good as we can do, since
-   it minimizes the time to do division by z.  We want the choice of z
-   to also result in a value for (a) that minimizes the computation of
-   the product (ax).  This is best achieved if (a) has a regular bit
-   pattern (so the multiplication can be done with shifts and adds).
-   The value of (a) also needs to be less than 2**32 so the product is
-   always guaranteed to fit in 2 words.
-
-   In actual practice, the following should be done:
-
-   1) For negative x, you should take the absolute value and remember
-   .  the fact so that the result can be negated.  This obviously does
-   .  not apply in the unsigned case.
-   2) For even y, you should factor out the power of 2 that divides y
-   .  and divide x by it.  You can then proceed by dividing by the
-   .  odd factor of y.
-
-   Here is a table of some odd values of y, and corresponding choices
-   for z which are "good".
-
-    y	  z	  r	 a (hex)     max x (hex)
-
-    3	2**32	  1	55555555      100000001
-    5	2**32	  1	33333333      100000003
-    7  2**24-1	  0	  249249     (infinite)
-    9  2**24-1	  0	  1c71c7     (infinite)
-   11  2**20-1	  0	   1745d     (infinite)
-   13  2**24-1	  0	  13b13b     (infinite)
-   15	2**32	  1	11111111      10000000d
-   17	2**32	  1	 f0f0f0f      10000000f
-
-   If r is 1, then b = a+r-1 = a.  This simplifies the computation
-   of (ax+b), since you can compute (x+1)(a) instead.  If r is 0,
-   then b = 0 is ok to use which simplifies (ax+b).
-
-   The bit patterns for 55555555, 33333333, and 11111111 are obviously
-   very regular.  The bit patterns for the other values of a above are:
-
-    y	   (hex)	  (binary)
-
-    7	  249249  001001001001001001001001  << regular >>
-    9	  1c71c7  000111000111000111000111  << regular >>
-   11	   1745d  000000010111010001011101  << irregular >>
-   13	  13b13b  000100111011000100111011  << irregular >>
-
-   The bit patterns for (a) corresponding to (y) of 11 and 13 may be
-   too irregular to warrant using this method.
-
-   When z is a power of 2 minus 1, then the division by z is slightly
-   more complicated, involving an iterative solution.
-
-   The code presented here solves division by 1 through 17, except for
-   11 and 13. There are algorithms for both signed and unsigned
-   quantities given.
-
-   TIMINGS (cycles)

-   .  16	4	   4	     2
-   .  17       16	  18	    16
-
-   Now, the algorithm for 7, 9, and 14 is an iterative one.  That is,
-   a loop body is executed until the tentative quotient is 0.  The
-   number of times the loop body is executed varies depending on the
-   dividend, but is never more than two times.	If the dividend is
-   less than the divisor, then the loop body is not executed at all.
-   Each iteration adds 4 cycles to the timings.

-   .  14       21+4n	 22+4n	   20+4n
-
-   To give an idea of how the number of iterations varies, here is a

-/* DIVISION BY DIVISORS OF FFFFFF, and powers of 2 times these
-   includes 7,9 and also 14
-
-
-   z = 2**24-1
-   r = z mod x = 0
-
-   so choose b = 0
-
-   Also, in order to divide by z = 2**24-1, we approximate by dividing
-   by (z+1) = 2**24 (which is easy), and then correcting.
-
-   (ax) = (z+1)q' + r
-   .	= zq' + (q'+r)
-
-   So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
-   Then the true remainder of (ax)/z is (q'+r).  Repeat the process
-   with this new remainder, adding the tentative quotients together,
-   until a tentative quotient is 0 (and then we are done).  There is
-   one last correction to be done.  It is possible that (q'+r) = z.
-   If so, then (q'+r)/(z+1) = 0 and it looks like we are done.	But,
-   in fact, we need to add 1 more to the quotient.  Now, it turns
-   out that this happens if and only if the original value x is
-   an exact multiple of y.  So, to avoid a three instruction test at
-   the end, instead use 1 instruction to add 1 to x at the beginning.  */

-	  a video (VGA) card on a PCI or AGP bus. Enabling write-combining

-	  before bursting over the PCI/AGP bus. This can increase performance

-
-	  This code has a reasonably generic interface so that similar
-	  control registers on other processors can be easily supported
-	  as well.
-
-	  Saying Y here also fixes a problem with buggy SMP BIOSes which only
-	  set the MTRRs for the boot CPU and not for the secondary CPUs. This

-	  support.  As of this writing the exact hardware interface is
-	  strongly in flux, so no good recommendation can be made.

-config CRASH_DUMP
-	bool "kernel crash dumps (EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-	  Generate crash dump after being started by kexec.
-	  This should be normally only set in special crash dump kernels
-	  which are loaded in the main kernel with kexec-tools into
-	  a specially reserved region and then later executed after
-	  a crash by kdump/kexec. The crash dump kernel must be compiled
-	  to a memory address not used by the main kernel or BIOS using
-	  PHYSICAL_START, or it must be built as a relocatable image
-	  (CONFIG_RELOCATABLE=y).
-	  For more details see Documentation/kdump/kdump.txt
-
-config RELOCATABLE
-	bool "Build a relocatable kernel (EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-	  Builds a relocatable kernel. This enables loading and running
-	  a kernel binary from a different physical address than it has
-	  been compiled for.
-
-	  One use is for the kexec on panic case where the recovery kernel
-	  must live at a different physical address than the primary
-	  kernel.
-
-	  Note: If CONFIG_RELOCATABLE=y, then the kernel runs from the address
-	  it has been loaded at and the compile time physical address
-	  (CONFIG_PHYSICAL_START) is ignored.
-
-config PHYSICAL_START
-	hex "Physical address where the kernel is loaded" if (EMBEDDED || CRASH_DUMP)
-	default "0x200000"
-	help
-	  This gives the physical address where the kernel is loaded. It
-	  should be aligned to 2MB boundary.
-
-	  If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
-	  bzImage will decompress itself to above physical address and
-	  run from there. Otherwise, bzImage will run from the address where
-	  it has been loaded by the boot loader and will ignore above physical
-	  address.
-
-	  In normal kdump cases one does not have to set/change this option
-	  as now bzImage can be compiled as a completely relocatable image
-	  (CONFIG_RELOCATABLE=y) and be used to load and run from a different
-	  address. This option is mainly useful for the folks who don't want
-	  to use a bzImage for capturing the crash dump and want to use a
-	  vmlinux instead.
-
-	  So if you are using bzImage for capturing the crash dump, leave
-	  the value here unchanged to 0x200000 and set CONFIG_RELOCATABLE=y.
-	  Otherwise if you plan to use vmlinux for capturing the crash dump
-	  change this value to start of the reserved region (Typically 16MB
-	  0x1000000). In other words, it can be set based on the "X" value as
-	  specified in the "crashkernel=YM@XM" command line boot parameter
-	  passed to the panic-ed kernel. Typically this parameter is set as
-	  crashkernel=64M@16M. Please take a look at
-	  Documentation/kdump/kdump.txt for more details about crash dumps.
-
-	  Usage of bzImage for capturing the crash dump is advantageous as
-	  one does not have to build two kernels. Same kernel can be used
-	  as production kernel and capture kernel.
-
-	  Don't change this unless you know what you are doing.
-
-config SECCOMP
-	bool "Enable seccomp to safely compute untrusted bytecode"
-	depends on PROC_FS
-	default y
-	help
-	  This kernel feature is useful for number crunching applications
-	  that may need to compute untrusted bytecode during their
-	  execution. By using pipes or other transports made available to
-	  the process as file descriptors supporting the read/write
-	  syscalls, it's possible to isolate those applications in
-	  their own address space using seccomp. Once seccomp is
-	  enabled via /proc/<pid>/seccomp, it cannot be disabled
-	  and the task is only allowed to execute a few safe syscalls
-	  defined by each seccomp mode.
-
-	  If unsure, say Y. Only embedded should say N here.
-
-config CC_STACKPROTECTOR
-	bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-         This option turns on the -fstack-protector GCC feature. This
-	  feature puts, at the beginning of critical functions, a canary
-	  value on the stack just before the return address, and validates
-	  the value just before actually returning.  Stack based buffer
-	  overflows (that need to overwrite this return address) now also
-	  overwrite the canary, which gets detected and the attack is then
-	  neutralized via a kernel panic.
-
-	  This feature requires gcc version 4.2 or above, or a distribution
-	  gcc with the feature backported. Older versions are automatically
-	  detected and for those versions, this configuration option is ignored.
-
-config CC_STACKPROTECTOR_ALL
-	bool "Use stack-protector for all functions"
-	depends on CC_STACKPROTECTOR
-	help
-	  Normally, GCC only inserts the canary value protection for
-	  functions that use large-ish on-stack buffers. By enabling
-	  this option, GCC will be asked to do this for ALL functions.

  *
  * This is the IDE probe module, as evolved from hd.c and ide.c.
  *
- * Version 1.00		move drive probing code from ide.c to ide-probe.c
- * Version 1.01		fix compilation problem for m68k
- * Version 1.02		increase WAIT_PIDENTIFY to avoid CD-ROM locking at boot
- *			 by Andrea Arcangeli
- * Version 1.03		fix for (hwif->chipset == ide_4drives)
- * Version 1.04		fixed buggy treatments of known flash memory cards
- *
- * Version 1.05		fix for (hwif->chipset == ide_pdc4030)
- *			added ide6/7/8/9
- *			allowed for secondary flash card to be detectable
- *			 with new flag : drive->ata_flash : 1;
- * Version 1.06		stream line request queue and prep for cascade project.
- * Version 1.07		max_sect <= 255; slower disks would get behind and
- * 			then fall over when they get to 256.	Paul G.
- * Version 1.10		Update set for new IDE. drive->id is now always
- *			valid after probe time even with noprobe

- * Forcing mixed mode for status/control lines if not all pins are used.
- *
- * Revision 1.15  2003/06/13 09:43:01  johana
- * Merged in the following changes from os/linux/arch/cris/drivers/serial.c
- * + some minor changes to reduce diff.
- *
- * Revision 1.49  2003/05/30 11:31:54  johana
- * Merged in change-branch--serial9bit that adds CMSPAR support for sticky
- * parity (mark/space)
- *
- * Revision 1.48  2003/05/30 11:03:57  johana
- * Implemented rs_send_xchar() by disabling the DMA and writing manually.
- * Added e100_disable_txdma_channel() and e100_enable_txdma_channel().
- * Fixed rs_throttle() and rs_unthrottle() to properly call rs_send_xchar
- * instead of setting info->x_char and check the CRTSCTS flag before
- * controlling the rts pin.
- *
- * Revision 1.14  2003/04/09 08:12:44  pkj
- * Corrected typo changes made upstream.
- *
- * Revision 1.13  2003/04/09 05:20:47  starvik
- * Merge of Linux 2.5.67
- *
- * Revision 1.11  2003/01/22 06:48:37  starvik
- * Fixed warnings issued by GCC 3.2.1
- *
- * Revision 1.9  2002/12/13 09:07:47  starvik
- * Alert user that RX_TIMEOUT_TICKS==0 doesn't work
- *
- * Revision 1.8  2002/12/11 13:13:57  starvik
- * Added arch/ to v10 specific includes
- * Added fix from Linux 2.4 in serial.c (flush_to_flip_buffer)
- *
- * Revision 1.7  2002/12/06 07:13:57  starvik
- * Corrected work queue stuff
- * Removed CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST
- *
- * Revision 1.6  2002/11/21 07:17:46  starvik
- * Change static inline to extern inline where otherwise outlined with gcc-3.2
- *
- * Revision 1.5  2002/11/14 15:59:49  starvik
- * Linux 2.5 port of the latest serial driver from 2.4. The work queue stuff
- * probably doesn't work yet.
- *
- * Revision 1.42  2002/11/05 09:08:47  johana
- * Better implementation of rs_stop() and rs_start() that uses the XOFF
- * register to start/stop transmission.
- * change_speed() also initilises XOFF register correctly so that
- * auto_xoff is enabled when IXON flag is set by user.
- * This gives fast XOFF response times.
- *
- * Revision 1.41  2002/11/04 18:40:57  johana
- * Implemented rs_stop() and rs_start().
- * Simple tests using hwtestserial indicates that this should be enough
- * to make it work.
- *
- * Revision 1.40  2002/10/14 05:33:18  starvik
- * RS-485 uses fast timers even if SERIAL_FAST_TIMER is disabled
- *
- * Revision 1.39  2002/09/30 21:00:57  johana
- * Support for CONFIG_ETRAX_SERx_DTR_RI_DSR_CD_MIXED where the status and
- * control pins can be mixed between PA and PB.
- * If no serial port uses MIXED old solution is used
- * (saves a few bytes and cycles).
- * control_pins struct uses masks instead of bit numbers.
- * Corrected dummy values and polarity in line_info() so
- * /proc/tty/driver/serial is now correct.
- * (the E100_xxx_GET() macros is really active low - perhaps not obvious)
- *
- * Revision 1.38  2002/08/23 11:01:36  starvik
- * Check that serial port is enabled in all interrupt handlers to avoid
- * restarts of DMA channels not assigned to serial ports
- *
- * Revision 1.37  2002/08/13 13:02:37  bjornw
- * Removed some warnings because of unused code
- *
- * Revision 1.36  2002/08/08 12:50:01  starvik
- * Serial interrupt is shared with synchronous serial port driver
- *
- * Revision 1.35  2002/06/03 10:40:49  starvik
- * Increased RS-485 RTS toggle timer to 2 characters
- *
- * Revision 1.34  2002/05/28 18:59:36  johana
- * Whitespace and comment fixing to be more like etrax100ser.c 1.71.
- *
- * Revision 1.33  2002/05/28 17:55:43  johana
- * RS-485 uses FAST_TIMER if enabled, and starts a short (one char time)
- * timer from tranismit_chars (interrupt context).
- * The timer toggles RTS in interrupt context when expired giving minimum
- * latencies.
- *
- * Revision 1.32  2002/05/22 13:58:00  johana
- * Renamed rs_write() to raw_write() and made it inline.
- * New rs_write() handles RS-485 if configured and enabled
- * (moved code from e100_write_rs485()).
- * RS-485 ioctl's uses copy_from_user() instead of verify_area().
- *
- * Revision 1.31  2002/04/22 11:20:03  johana
- * Updated copyright years.
- *
- * Revision 1.30  2002/04/22 09:39:12  johana
- * RS-485 support compiles.
- *
- * Revision 1.29  2002/01/14 16:10:01  pkj
- * Allocate the receive buffers dynamically. The static 4kB buffer was
- * too small for the peaks. This means that we can get rid of the extra
- * buffer and the copying to it. It also means we require less memory
- * under normal operations, but can use more when needed (there is a
- * cap at 64kB for safety reasons). If there is no memory available
- * we panic(), and die a horrible death...
- *
- * Revision 1.28  2001/12/18 15:04:53  johana
- * Cleaned up write_rs485() - now it works correctly without padding extra
- * char.
- * Added sane default initialisation of rs485.
- * Added #ifdef around dummy variables.
- *
- * Revision 1.27  2001/11/29 17:00:41  pkj
- * 2kB seems to be too small a buffer when using 921600 bps,
- * so increase it to 4kB (this was already done for the elinux
- * version of the serial driver).
- *
- * Revision 1.26  2001/11/19 14:20:41  pkj
- * Minor changes to comments and unused code.
- *
- * Revision 1.25  2001/11/12 20:03:43  pkj
- * Fixed compiler warnings.
- *
- * Revision 1.24  2001/11/12 15:10:05  pkj
- * Total redesign of the receiving part of the serial driver.
- * Uses eight chained descriptors to write to a 4kB buffer.
- * This data is then serialised into a 2kB buffer. From there it
- * is copied into the TTY's flip buffers when they become available.
- * A lot of copying, and the sizes of the buffers might need to be
- * tweaked, but all in all it should work better than the previous
- * version, without the need to modify the TTY code in any way.
- * Also note that erroneous bytes are now correctly marked in the
- * flag buffers (instead of always marking the first byte).
- *
- * Revision 1.23  2001/10/30 17:53:26  pkj
- * * Set info->uses_dma to 0 when a port is closed.
- * * Mark the timer1 interrupt as a fast one (SA_INTERRUPT).
- * * Call start_flush_timer() in start_receive() if
- *   CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST is defined.
- *
- * Revision 1.22  2001/10/30 17:44:03  pkj
- * Use %lu for received and transmitted counters in line_info().
- *
- * Revision 1.21  2001/10/30 17:40:34  pkj
- * Clean-up. The only change to functionality is that
- * CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS(=5) is used instead of
- * MAX_FLUSH_TIME(=8).
- *
- * Revision 1.20  2001/10/30 15:24:49  johana
- * Added char_time stuff from 2.0 driver.
- *
- * Revision 1.19  2001/10/30 15:23:03  johana
- * Merged with 1.13.2 branch + fixed indentation
- * and changed CONFIG_ETRAX100_XYS to CONFIG_ETRAX_XYZ
- *
- * Revision 1.18  2001/09/24 09:27:22  pkj
- * Completed ext_baud_table[] in cflag_to_baud() and cflag_to_etrax_baud().
- *
- * Revision 1.17  2001/08/24 11:32:49  ronny
- * More fixes for the CONFIG_ETRAX_SERIAL_PORT0 define.
- *
- * Revision 1.16  2001/08/24 07:56:22  ronny
- * Added config ifdefs around ser0 irq requests.
- *
- * Revision 1.15  2001/08/16 09:10:31  bjarne
- * serial.c - corrected the initialization of rs_table, the wrong defines
- *            where used.
- *            Corrected a test in timed_flush_handler.
- *            Changed configured to enabled.
- * serial.h - Changed configured to enabled.
- *
- * Revision 1.14  2001/08/15 07:31:23  bjarne
- * Introduced two new members to the e100_serial struct.
- * configured - Will be set to 1 if the port has been configured in .config
- * uses_dma   - Should be set to 1 if the port uses DMA. Currently it is set
- *              to 1
- *              when a port is opened. This is used to limit the DMA interrupt
- *              routines to only manipulate DMA channels actually used by the
- *              serial driver.
- *
- * Revision 1.13.2.2  2001/10/17 13:57:13  starvik
- * Receiver was broken by the break fixes
- *
- * Revision 1.13.2.1  2001/07/20 13:57:39  ronny
- * Merge with new stuff from etrax100ser.c. Works but haven't checked stuff
- * like break handling.
- *
- * Revision 1.13  2001/05/09 12:40:31  johana
- * Use DMA_NBR and IRQ_NBR defines from dma.h and irq.h
- *
- * Revision 1.12  2001/04/19 12:23:07  bjornw
- * CONFIG_RS485 -> CONFIG_ETRAX_RS485
- *
- * Revision 1.11  2001/04/05 14:29:48  markusl
- * Updated according to review remarks i.e.
- * -Use correct types in port structure to avoid compiler warnings
- * -Try to use IO_* macros whenever possible
- * -Open should never return -EBUSY
- *
- * Revision 1.10  2001/03/05 13:14:07  bjornw
- * Another spelling fix
- *
- * Revision 1.9  2001/02/23 13:46:38  bjornw
- * Spellling check
- *
- * Revision 1.8  2001/01/23 14:56:35  markusl
- * Made use of ser1 optional
- * Needed by USB
- *
- * Revision 1.7  2001/01/19 16:14:48  perf
- * Added kernel options for serial ports 234.
- * Changed option names from CONFIG_ETRAX100_XYZ to CONFIG_ETRAX_XYZ.
- *
- * Revision 1.6  2000/11/22 16:36:09  bjornw
- * Please marketing by using the correct case when spelling Etrax.
- *
- * Revision 1.5  2000/11/21 16:43:37  bjornw
- * Fixed so it compiles under CONFIG_SVINTO_SIM
- *
- * Revision 1.4  2000/11/15 17:34:12  bjornw
- * Added a timeout timer for flushing input channels. The interrupt-based
- * fast flush system should be easy to merge with this later (works the same
- * way, only with an irq instead of a system timer_list)
- *
- * Revision 1.3  2000/11/13 17:19:57  bjornw
- * * Incredibly, this almost complete rewrite of serial.c worked (at least
- *   for output) the first time.
- *
- *   Items worth noticing:
- *
- *      No Etrax100 port 1 workarounds (does only compile on 2.4 anyway now)
- *      RS485 is not ported (why can't it be done in userspace as on x86 ?)
- *      Statistics done through async_icount - if any more stats are needed,
- *      that's the place to put them or in an arch-dep version of it.
- *      timeout_interrupt and the other fast timeout stuff not ported yet
- *      There be dragons in this 3k+ line driver
- *
- * Revision 1.2  2000/11/10 16:50:28  bjornw
- * First shot at a 2.4 port, does not compile totally yet
- *
- * Revision 1.1  2000/11/10 16:47:32  bjornw
- * Added verbatim copy of rev 1.49 etrax100ser.c from elinux
- *
- * Revision 1.49  2000/10/30 15:47:14  tobiasa
- * Changed version number.
- *
- * Revision 1.48  2000/10/25 11:02:43  johana
- * Changed %ul to %lu in printf's
- *
- * Revision 1.47  2000/10/18 15:06:53  pkj
- * Compile correctly with CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST and
- * CONFIG_ETRAX_SERIAL_PROC_ENTRY together.
- * Some clean-up of the /proc/serial file.
- *
- * Revision 1.46  2000/10/16 12:59:40  johana
- * Added CONFIG_ETRAX_SERIAL_PROC_ENTRY for statistics and debug info.
- *
- * Revision 1.45  2000/10/13 17:10:59  pkj
- * Do not flush DMAs while flipping TTY buffers.
- *
- * Revision 1.44  2000/10/13 16:34:29  pkj
- * Added a delay in ser_interrupt() for 2.3ms when an error is detected.
- * We do not know why this delay is required yet, but without it the
- * irmaflash program does not work (this was the program that needed
- * the ser_interrupt() to be needed in the first place). This should not
- * affect normal use of the serial ports.
- *
- * Revision 1.43  2000/10/13 16:30:44  pkj
- * New version of the fast flush of serial buffers code. This time
- * it is localized to the serial driver and uses a fast timer to
- * do the work.
- *
- * Revision 1.42  2000/10/13 14:54:26  bennyo
- * Fix for switching RTS when using rs485
- *
- * Revision 1.41  2000/10/12 11:43:44  pkj
- * Cleaned up a number of comments.
- *
- * Revision 1.40  2000/10/10 11:58:39  johana
- * Made RS485 support generic for all ports.
- * Toggle rts in interrupt if no delay wanted.
- * WARNING: No true transmitter empty check??
- * Set d_wait bit when sending data so interrupt is delayed until
- * fifo flushed. (Fix tcdrain() problem)
- *
- * Revision 1.39  2000/10/04 16:08:02  bjornw
- * * Use virt_to_phys etc. for DMA addresses
- * * Removed CONFIG_FLUSH_DMA_FAST hacks
- * * Indentation fix
- *
- * Revision 1.38  2000/10/02 12:27:10  mattias
- * * added variable used when using fast flush on serial dma.
- *   (CONFIG_FLUSH_DMA_FAST)
- *
- * Revision 1.37  2000/09/27 09:44:24  pkj
- * Uncomment definition of SERIAL_HANDLE_EARLY_ERRORS.
- *
- * Revision 1.36  2000/09/20 13:12:52  johana
- * Support for CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS:
- *   Number of timer ticks between flush of receive fifo (1 tick = 10ms).
- *   Try 0-3 for low latency applications. Approx 5 for high load
- *   applications (e.g. PPP). Maybe this should be more adaptive some day...
- *
- * Revision 1.35  2000/09/20 10:36:08  johana
- * Typo in get_lsr_info()
- *
- * Revision 1.34  2000/09/20 10:29:59  johana
- * Let rs_chars_in_buffer() check fifo content as well.
- * get_lsr_info() might work now (not tested).
- * Easier to change the port to debug.
- *
- * Revision 1.33  2000/09/13 07:52:11  torbjore
- * Support RS485
- *
- * Revision 1.32  2000/08/31 14:45:37  bjornw
- * After sending a break we need to reset the transmit DMA channel
- *
- * Revision 1.31  2000/06/21 12:13:29  johana
- * Fixed wait for all chars sent when closing port.
- * (Used to always take 1 second!)
- * Added shadows for directions of status/ctrl signals.
- *
- * Revision 1.30  2000/05/29 16:27:55  bjornw
- * Simulator ifdef moved a bit
- *
- * Revision 1.29  2000/05/09 09:40:30  mattias
- * * Added description of dma registers used in timeout_interrupt
- * * Removed old code
- *
- * Revision 1.28  2000/05/08 16:38:58  mattias
- * * Bugfix for flushing fifo in timeout_interrupt
- *   Problem occurs when bluetooth stack waits for a small number of bytes
- *   containing an event acknowledging free buffers in bluetooth HW
- *   As before, data was stuck in fifo until more data came on uart and
- *   flushed it up to the stack.
- *
- * Revision 1.27  2000/05/02 09:52:28  jonasd
- * Added fix for peculiar etrax behaviour when eop is forced on an empty
- * fifo. This is used when flashing the IRMA chip. Disabled by default.
- *
- * Revision 1.26  2000/03/29 15:32:02  bjornw
- * 2.0.34 updates
- *
- * Revision 1.25  2000/02/16 16:59:36  bjornw
- * * Receive DMA directly into the flip-buffer, eliminating an intermediary
- *   receive buffer and a memcpy. Will avoid some overruns.
- * * Error message on debug port if an overrun or flip buffer overrun occurs.
- * * Just use the first byte in the flag flip buffer for errors.
- * * Check for timeout on the serial ports only each 5/100 s, not 1/100.
- *
- * Revision 1.24  2000/02/09 18:02:28  bjornw
- * * Clear serial errors (overrun, framing, parity) correctly. Before, the
- *   receiver would get stuck if an error occurred and we did not restart
- *   the input DMA.
- * * Cosmetics (indentation, some code made into inlines)
- * * Some more debug options
- * * Actually shut down the serial port (DMA irq, DMA reset, receiver stop)
- *   when the last open is closed. Corresponding fixes in startup().
- * * rs_close() "tx FIFO wait" code moved into right place, bug & -> && fixed
- *   and make a special case out of port 1 (R_DMA_CHx_STATUS is broken for that)
- * * e100_disable_rx/enable_rx just disables/enables the receiver, not RTS
- *
- * Revision 1.23  2000/01/24 17:46:19  johana
- * Wait for flush of DMA/FIFO when closing port.
- *
- * Revision 1.22  2000/01/20 18:10:23  johana
- * Added TIOCMGET ioctl to return modem status.
- * Implemented modem status/control that works with the extra signals
- * (DTR, DSR, RI,CD) as well.
- * 3 different modes supported:
- * ser0 on PB (Bundy), ser1 on PB (Lisa) and ser2 on PA (Bundy)
- * Fixed DEF_TX value that caused the serial transmitter pin (txd) to go to 0 when
- * closing the last filehandle, NASTY!.
- * Added break generation, not tested though!
- * Use IRQF_SHARED when request_irq() for ser2 and ser3 (shared with) par0 and par1.
- * You can't use them at the same time (yet..), but you can hopefully switch
- * between ser2/par0, ser3/par1 with the same kernel config.
- * Replaced some magic constants with defines
- *
