IMHO, we really only want to unmask RTEs # for PRTs we might actually use. This moves the interrupt # distribution here too. # # - When changing a vector from edge to level, call register_intr() # to do it so all the data structures get set correctly. If we # have to guess how to setup an interupt and get it wrong, this # should close some holes in changing it back to the correct type. # # - Register the HCDP interrupt in 8250_hcdp - this is where we have # to guess the polarity/trigger. The real handler will get fixed # up via PCI setup or ACPI namespace serial support, this gets it # associated w/ the port at setup.

A NULL 4th arg to semtimedop() should result in no timeout # being used (like a straight semop() call) rather than in an EFAULT error. # # The second problem was that a legitimate semtimedop() with a timeout was # also resulting in an EFAULT because the fetch of the internal timespec # strucure by sys_semtimedop() from semtimedop32()'s kernel stack was # treated as an invalid user-data reference. This requires temporarily # switching the addressing limit with set_fs(), further requiring that # appropriate parameter checking by performed prior to the switch. # # The const qualifier was removed from the (struct compat_timespec *) arg # to semtimedop32() so that the call to get_compat_timespec() wouldn't # generate a compilation warning. # -------------------------------------------- # 03/05/06 davidm@tiger.hpl.hp.com 1.971.102.36 # ia64: Manual merge of Bjorn Helgaas' sba_iommu patch to make it use seq_file. # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1067.1.1 # fix syntax error in ncr53c8xx from hch conversion # -------------------------------------------- # 03/05/06 greg@kroah.com 1.1063.6.1 # Merge gregkh@kernel.bkbits.net:/home/gregkh/linux/pci-2.5 # into kroah.com:/home/greg/linux/BK/pci-2.5 # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1067.1.2 # fix missed conversion of to_scsi_host -> dev_to_shost in sim710 # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1067.1.3 # add missing asm/io.h to scsi/dc395x.c # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1069 # Merge raven.il.steeleye.com:/home/jejb/BK/scsi-aic-2.5 # into raven.il.steeleye.com:/home/jejb/BK/scsi-misc-2.5 # -------------------------------------------- # 03/05/06 roland@frob.com 1.1063.7.1 # [PATCH] core dump psinfo.pr_sname letter fix # # This patch makes the state letter in the pr_sname field in core dumps # correct for stopped and zombie threads.

03/05/07 markh@osdl.org 1.1078 # [PATCH] New aacraid driver fixed. # # I have the new aacraid driver working on my system now. The patch is # against the 2.5.66 updates that you gave me. I made the following # changes: # # aachba.c aac_scsi_cmd() # There was a race accessing the scsicmd pointer accessing the host_lock. # I made a local pointer to the Scsi_Host so the spin_lock_irq after # aac_read wouldn't panic. I think that sometimes the I/O would be done # and the memory freed before returning invalidating the scsicmd pointer. # I made the same change in aac_io_done in case scsi_done had freed the # scsicmd memory before returning. # # comminit.c aac_alloc_comm() # AdapterFibsVirtualAddress was set to the virtual address of base. I # changed it to set it to the phys address. I compared this to code # pointed to by matt domsch on the aacraid devel list on the 5th. Its # aac_alloc_comm sets this variable to the phys address. This fixed the # probelem where the entry->addr was bad. Another was to fix it I guess # would be to leave this change alone and not try to convert the address # in aac_command_normal. # # dpcsup.c aac_response_normal() # Changed the bus_to_virt to the calculation we talked about last month. # dpcsup.c aac_command_normal() # Changed the bus_to_virt to the calculation. # -------------------------------------------- # 03/05/07 maxk@qualcomm.com 1.1063.12.4 # Merge bk://linux-bt.bkbits.net/marcel-2.5 # into qualcomm.com:/home/kernel/bt-2.5 # -------------------------------------------- # 03/05/07 torvalds@home.transmeta.com 1.1063.14.1 # Use "__attribute__" consistently. # -------------------------------------------- # 03/05/07 torvalds@home.transmeta.com 1.1063.14.2 # Allow external checkers to overrid the "cond_syscall()" macro. # -------------------------------------------- # 03/05/07 torvalds@home.transmeta.com 1.1063.14.3 # Support a "checking" mode for kernel builds, that runs a # user-supplied source checker on all C files before compiling # them. # # I'll release the actual checker once I've cleaned it up a # bit more (yay, all the copyright paperwork completed!) # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.14.4 # [PATCH] generic subarchitecture for ia32 # # From: Andi Kleen # # This patch adds an generic x86 subarchitecture. It is intended to provide # an dynamic interface for APIC drivers. There are already three subarchitectures # (bigsmp, summit, default) that only differ in how they drive the local APIC. # A fourth - Unisys ES7000 - is scheduled to be merged soon. # # The subarchitecture concept separated this nicely, but it has the big # drawback that they are compile time options. A Linux vendor cannot # ship own binary kernel rpms for all of these machines. Runtime probing # is needed instead. # # This patch adds a new "generic" subarchitecture that just acts as a # dynamic switching layer for APIC drivers. It only tries to virtualize # the APICs, no attempt is made to cover further incompatiblities. # This means machines like the Visual Workstation, pc9800 or # Voyager are not covered; but these are unlikely to be supported by # binary distributions anyways. # # The generic arch reuses the existing interface in mach_ipi / mach_mpparse.h / # mach_apic.h and just pulls it using some macros into an "struct genapic" # object. The main APIC code does not recognize it, it is all hidden # in the mach-generic include files. # # Auto detection of APIC types is supported in the usual way used by # existing ports like Summit - checking ACPI or mptables for specific # signatures - or it can be specified by the user using a new "apic=" # boot option. I also moved the DMI scan to before the generic # subarchitecture probe, so DMI could be used in future too to probe # specific machines. # # Some minor hacks were needed to avoid circular declaration of a few # symbols, but overall it's fairly clean. # # The patch has been tested on a Summit machine, an generic 4 virtual CPUs # Xeon and on an ES7000. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.14.5 # [PATCH] Fix .altinstructions linking failures # # From: Andi Kleen # # Some configs didn't link anymore because they got references from # .altinstructions to __exit functions.

The worst offender still left is devfs_register, it's prototype # is: # # devfs_handle_t devfs_register(devfs_handle_t dir, # const char *name, unsigned int flags, # unsigned int major, unsigned int minor, # umode_t mode, void *ops, void *info) # # Of these: # # - dir and flags are always zero # - the return value is never used # - info is only used in one driver which doesn't even need it for # operation # - umode_t always describes a character device # - name very often comes from a stack buffer we sprintf'ed into # # so obviously we really want a much simpler API instead. My first draft for # this was: # # int devfs_mk_cdev(dev_t dev, umode_t mode, # struct file_operations *fops, void *info, # const char *fmt, ...) # # this removes the unused argumens, switches to a proper dev_t for the device # number and allows to directly use a printf-like expression as name, getting # rid of the temporary buffers. # # Now Al has reappeared and put the first steps of his CIDR for charater device # on public ftp and we'll soon have a similar lookup object + fops mechanism in # generic code as we already habe for blockdevices, i.e. the devfs code to # assign fops from an entry will become superflous as generic code already does # it. That means the fops and info arguments are obsolete before they were # introduced, so I'd like to propose the following API instead: # # int devfs_mk_cdev(dev_t dev, umode_t mode, const char *fmt, ...) # # which is much nicer anyway. The educated reader will notice that this is # exactly the same prototype devfs_mk_bdev has so I'll probably get suggestions # to merge those two into some kind of devfs_mk_node soon. Personally I don't # like that as character and blockdevices are two really separate entinities # and I'll like to keep them as separate as possible. # # Example patch that introduces the API and converts drivers/input attached. # # Every driver which calls devfs_mk_cdev (about 50) needs conversion. Note # that the transition can happen in pieces - devfs_register continues to work # after this patch, it's just the plan to get rid of it in the end. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.14.18 # [PATCH] remove partition_name() # # From: Christoph Hellwig # # partition_name() is a variant of __bdevname() that caches results and # returns a pointrer to kmalloc()ed data instead of printing into a buffer. # Due to it's caching it gets utterly confused when the name for a dev_t # changes (can happen easily now with device mapper and probably in the # future with dynamic dev_t users). # # It's only used by the raid code and most calls are through a wrapper, # bdev_partition_name() which takes a struct block_device * that maybe be # NULL. # # The patch below changes the bdev_partition_name() to call bdevname() if # possible and the other calls where we really have nothing more than a dev_t # to __bdevname. # # Btw, it would be nice if someone who knows the md code a bit better than me # could remove bdev_partition_name() in favour of direct calls to bdevname() # where possible - that would also get rid of the returns pointer to string # on stack issue that this patch can't fix yet. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.14.19 # [PATCH] switch most remaining drivers over to devfs_mk_bdev # # From: Christoph Hellwig # # This is a pretty huge patch, but splitting it doesn't make a lot # of sense.. # # (USB may still need work) # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.14.20 # [PATCH] dvbdev fixes # # From: Monchi Abbad # # I found a mistake in the dvbdev.c file when creating the dvb /devfs files, # it created /dev/dvb/adapter0device0 instead of /dev/dvb/adapter0/device0. # But here is a simple fix. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.14.21 # [PATCH] access_ok() race fix for 80386. # # From: Manfred Spraul # # Real 80386 cpus ignore the write protected bit in the page tables when # running in supervisory mode. Thus the write protected bit must be checked by # software. The current implementation does that check during access_ok(). # This can result in data corruptions, if kswapd starts a swap-out between the # access_ok and the actual write operation. # # To fix this, the patch moves the check from access_ok() into # __copy_to_user_ll(), and redirects all user space writes into # __copy_to_user_ll(). The patch only affects kernels build for 80386 cpus. # Additionally, the patch removes the dead prototypes for __put_user_{1,2,4,8}. # # Due to the uninlining of access_ok, the .text segment is now ~ 8 kB shorter. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.14.22 # [PATCH] hold i_sem on swapfiles # # If a swapfile is ftruncated while in use, subsequent swapout will scribble on # the filesystem. # # This is a case of root-shoot-foot, but wrecking the fs is a fairly rude # response.

I ended up putting the accounting into a stack-local # structure which is pointed to by current->reclaim_state. # # One reason for this is that we can cleanly resurrect the current->local_pages # pool by putting it into struct reclaim_state. # # (current->local_pages was removed because the per-cpu page pools in the page # allocator largely duplicate its function.

This is because the installation of space # handlers can cause _REG methods to be run. Previously, the _REG methods # could potentially be run before ACPI mode was enabled. # # Fixed some memory leak issues related to address space handler and notify # handler installation. There were some problems with the reference count # mechanism caused by the fact that the handler objects are shared across # several namespace objects. # # Fixed a reported problem where reference counts within the namespace were # not properly updated when named objects created by method execution were # deleted. # # Fixed a reported problem where multiple SSDTs caused a deletion issue # during subsystem termination. Restructured the table data structures # to simplify the linked lists and the related code. # # Fixed a problem where the table ID associated with secondary tables (SSDTs) # was not being propagated into the namespace objects created by those # tables. This would only present a problem for tables that are unloaded # at run-time, however. # # Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE type as # the length parameter (instead of UINT32). # # Solved a long-standing problem where an ALREADY_EXISTS error appears on # various systems. This problem could happen when there are multiple # PCI_Config operation regions under a single PCI root bus. This doesnt # happen very frequently, but there are some systems that do this in the # ASL. # # Fixed a reported problem where the internal DeleteNode function was # incorrectly handling the case where a namespace node was the first in # the parents child list, and had additional peers (not the only child, # but first in the list of children.) # -------------------------------------------- # 03/05/12 davej@codemonkey.org.uk 1.1063.31.2 # [DRM] Intel i8xx DRM modules are dependant on their AGP counterparts. # Closes bugzilla #646 # -------------------------------------------- # 03/05/12 davej@tetrachloride.(none) 1.1063.35.1 # Merge tetrachloride.(none):/mnt/raid/src/kernel/2.5/bk-linus # into tetrachloride.(none):/mnt/raid/src/kernel/2.5/agpgart # -------------------------------------------- # 03/05/12 torvalds@penguin.transmeta.com 1.1063.2.33 # Use '#ifdef' to test for CONFIG_xxx variables, instead of depending # on undefined preprocessor symbols evaluating to zero. # # Make smpboot.c look like ANSI C with proper function declarations. # -------------------------------------------- # 03/05/12 torvalds@penguin.transmeta.com 1.1063.2.34 # Add user pointer annotations. # -------------------------------------------- # 03/05/12 agrover@groveronline.com 1.1063.36.1 # Merge groveronline.com:/root/bk/linux-2.5 # into groveronline.com:/root/bk/linux-acpi # -------------------------------------------- # 03/05/12 torvalds@penguin.transmeta.com 1.1063.2.35 # Use '#ifdef' to test for CONFIG_xxx variables, instead of # depending on undefined preprocessor symbols evaluating to zero. # # Make panic.c use proper function prototypes. # -------------------------------------------- # 03/05/12 torvalds@penguin.transmeta.com 1.1063.2.36 # Add user pointer annotations to core sysctl files. # -------------------------------------------- # 03/05/12 maxk@qualcomm.com 1.1063.37.1 # Merge bk://linux.bkbits.net/linux-2.5 # into qualcomm.com:/home/kernel/bt-2.5 # -------------------------------------------- # 03/05/12 davem@nuts.ninka.net 1.1063.38.1 # Merge nuts.ninka.net:/home/davem/src/BK/network-2.5 # into nuts.ninka.net:/home/davem/src/BK/net-2.5 # -------------------------------------------- # 03/05/12 shemminger@osdl.org 1.1063.38.2 # [BRIDGE]: Bridge timer performance enhancement. # -------------------------------------------- # 03/05/12 shemminger@osdl.org 1.1063.38.3 # [NET]: Network packet type using RCU. # * packet type converted from linked list to list_macro # * writer lock replaced with spin lock, readers use RCU # * add __dev_remove_pack for callers that cant sleep. # * af_packet changes to handle and sleeping requirements, and possible # races that could cause. # -------------------------------------------- # 03/05/12 shemminger@osdl.org 1.1063.38.4 # [BRLOCK]: Kill big reader locks, no longer used. # -------------------------------------------- # 03/05/12 shemminger@osdl.org 1.1063.38.5 # [IPV4/IPV6]: synchronize_kernel --> synchronize_net. # -------------------------------------------- # 03/05/12 davem@nuts.ninka.net 1.1063.38.6 # [BRLOCK]: Kill stray brlock.h references in sparc/sparc64 headers. # -------------------------------------------- # 03/05/12 jmorris@intercode.com.au 1.1063.38.7 # [IPSEC]: Implement proper IPIP tunnel handling for IPcomp. # -------------------------------------------- # 03/05/12 jmorris@intercode.com.au 1.1063.38.8 # [CRYPTO]: Fix config dependencies. # -------------------------------------------- # 03/05/12 kazunori@miyazawa.org 1.1063.38.9 # [IPV4]: Introduce ip6_append_data. # -------------------------------------------- # 03/05/12 torvalds@penguin.transmeta.com 1.1063.2.37 # Add user pointer annotations to socket, file IO and signal # handling. # # This pointed out a bug in x86 sys_rt_sigreturn(), btw. # -------------------------------------------- # 03/05/12 davidm@napali.hpl.hp.com 1.1063.2.38 # [PATCH] Add ia64 relocation types to elf.h and clean up # # There is a _lot_ of stuff in linux/elf.h that shouldn't be there. # # This moves the arch-specific stuff in linux/elf.h into the corresponding # asm header files. # -------------------------------------------- # 03/05/12 davem@nuts.ninka.net 1.1063.38.10 # [IPV6]: Fix two bugs in ip6_append_data changes. # -

In which # case current->mm has nothing to do with the mm which is being put in # mmput(). # # So rather than assuming that the mm which is being put is current->mm, we # need to calculate the virtual span of the mm. Add a new per-arch macro # MM_VM_SIZE() for that. # # Some platforms can currently go BUG over this (where?). sparc64 is safe # because our TASK_SIZE is constant. # # Platforms such as ia64 should stick the VM extent inside of mm_struct, I'd # suggest adding it to mm_context_t. # # 1) TASK_SIZE means what is valid for mmap()'s in the processes # address space # # 2) MM_VM_SIZE means where things might be mapped for a MM, including # private implementation-specific areas created by the kernel # which the user cannot access # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.2.62 # [PATCH] semop race fix # # From: Mingming Cao # # Basically, freeary() is called with the spinlock for that semaphore set # hold. But after the semaphore set is removed from the ID array by # calling sem_rmid(), there is no lock to protect the waiting queue for # that semaphore set. So, if a waiter is woken up by a signal (not by the # wakeup from freeary()), it will check the q->status and q->prev fields. # At that moment, freeary() may not have a chance to update those fields # yet. # # static void freeary (int id) # { # ....... # sma = sem_rmid(id); # # ...... # /* Wake up all pending processes and let them fail with EIDRM.*/ # for (q = sma->sem_pending; q; q = q->next) { # q->status = -EIDRM; # q->prev = NULL; # wake_up_process(q->sleeper); /* doesn't sleep */ # } # sem_unlock(sma); # ...... # } # # So I propose move sem_rmid() after the loop of waking up every waiters. # That could gurantee that when the waiters are woke up, the updates for # q->status and q->prev have already done.

In the current kernel it is unclear as to weather the # value being passed to the function is a cpu mask or valid apic id. In # irq_affinity_write_proc the kernel passes on a cpu mask but the kirqd thread # passes on logical apic ids. In flat apic mode this is not an issue because a # cpu mask represents the apic value. However in clustered apic mode the cpu # mask is very different from the logical apic id. # # This is an attempt to do the right thing for clustered apics. I clarify that # the value being passed to set_ioapic_affinity is a cpu mask not a apicid. # Set_ioapic_affinity will do the conversion to logical apic ids. Since many # cpu masks don't map to valid apicids in clustered apic mode TARGET_CPUS is # used as a default value when such a situation occurs. I think this is a good # step in making irq_affinity clustered apic safe. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.2.65 # [PATCH] provide user feedback for emergency sync and remount # # People like to see when the emergency sync and emergency remount operations # have completed. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.2.66 # [PATCH] copy_process return value fix # # Rather than assuming that all the things which copy_process() calls want to # return -ENOMEM, correctly propagate the return values. # # This turns out to be a no-op at present. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.2.67 # [PATCH] de_thread memory corruption fix # # From: Manfred Spraul # # de_thread calls list_del(¤t->tasks), but current->tasks was never # added to the task list.

As things stand, # the presence of a vm_area in the vmlist protects from allocators other than # the owner examining the ptes in that area. This puts an ordering constraint # on unmapping, so that allocators are required to unmap areas before removing # them from the list or otherwise dropping the lock. # # Currently, unmap_vm_area() is done outside the lock and after the area is # removed, which as we've seen from Felix von Leitner's test is oopsable. # # The following patch folds calls to unmap_vm_area() into remove_vm_area() to # reinstate what are essentially the 2.4.x semantics of vfree(). This renders # a number of unmap_vm_area() calls unnecessary (and in fact oopsable since # they wipe ptes from later allocations). It's an open question as to whether # this is sufficiently performant, but it is the minimally invasive approach. # The more performant alternative is to provide the right API hooks to wipe the # vmalloc() area clean before removing them from the list, using the ownership # of the area to eliminate holding the vmlist_lock for the duration of the # unmapping. If it proves to be necessary wli is on standby to implement it. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.2.69 # [PATCH] Reserve the ext2/ext3 EAs for the Lustre filesystem # # From: Andreas Dilger # # Below are the patches which reserve the Lustre EA index.

The more CPUs, the more delays. # # The cause of the problem is that the current signal wakeup # implementation is racy in kernel/signal.c:signal_wake_up(): # # if (t->state == TASK_RUNNING) # kick_if_running(t); # ... # if (t->state & mask) { # wake_up_process(t); # return; # } # # If thread (or process) 't' is woken up on another CPU right after the # TASK_RUNNING check, and thread starts to run, then the wake_up_process() # here will do nothing, and the signal stays pending up until the thread # will call into the kernel next time - which can be up to 200 msecs # later. # # The solution is to do the 'kicking' of a running thread on a remote CPU # atomically with the wakeup. For this i've added wake_up_process_kick(). # There is no slowdown for the other wakeup codepaths, the new flag to # try_to_wake_up() is compiled off for them. Some other subsystems might # want to use this wakeup facility as well in the future (eg. AIO). # # In fact this race triggers quite often under Volanomark rusg, with this # change added, Volanomark performance is up from 500-800 to 2000-3000, on # a 4-way x86 box. # -------------------------------------------- # 03/05/19 mingo@elte.hu 1.1164.1.3 # [PATCH] scheduler cleanup # # This removes the unused requeueing code. # -------------------------------------------- # 03/05/19 mingo@elte.hu 1.1164.1.4 # [PATCH] sync wakeup on UP # # This fixes the scheduler's sync-wakeup code to be consistent on UP as # well. # # Right now there's a behavioral difference between an UP kernel and an # SMP kernel running on a UP box: sync wakeups (which are only activated # on SMP) can cause a wakeup of a higher prio task, without preemption. # On UP kernels this does not happen. This difference in wakeup behavior # is bad. # # This patch activates sync wakeups on UP as well - in the cases sync # wakeups are done the waker knows that it will schedule away soon, so # this 'delay preemption' decision is correct on UP as well. # -------------------------------------------- # 03/05/19 david-b@pacbell.net 1.1155.3.1 # [PATCH] USB: usbtest, talk to user mode "firmware" # # Supports some user-mode testing "firmware". # -------------------------------------------- # 03/05/19 mingo@elte.hu 1.1164.1.5 # [PATCH] Fix lost scheduler rebalances # # This fixes a race noticed by Mike Galbraith: the scheduler can lose a # rebalance tick if some task happens to not be rescheduled in time.

Several speedups. # # Only changes x86-64 specific files. # # - Use private copy of siginfo.h (for si_band) # - Align 32bit vsyscall coredump (from Roland McGrath) # - First steps towards 64bit vsyscall coredump (not working yet) # - Use in kernel trampoline for signals # - Merge APIC pm update from Pavel/Mikael # - Security fix for ioperm (from i386) # - Reenable vsyscall dumping for 32bit coredumps # - Fix bugs in 32bit coredump that could lead to oopses. # - Fix 64bit vsyscalls # - Revert change in pci-gart.c: pci_alloc_consistent must use an # 0xffffffff mask hardcoded. # - Fix bug in noexec= option handling # - Export fake_node # - Cleanups from Pavel # - Disable 32bit vsyscall coredump again. Still has some problems. # - Implement new noexec= and noexec32= options to give a wide choice # of support for non executable mappings for 32bit and 64bit processes. # The default is now to honor PROT_EXEC, but mark stack and heap # PROT_EXEC. # - 32bit emulation changes from Pavel: use compat_* types. # - (2.4) Use physical address for GART register. # - Convert debugreg array to individual members and clean up ptrace # access. This saves 16 byte per task. # - (2.4) Use new streamlined context switch code. This avoids a # pipeline stall and pushes the register saving to C code. # - Save flags register in context switch # - Clean up SMP early bootup. Remove some unnecessary code. # - (2.4) Process numa= option early # - (2.4) Merge 2.4 clear_page, copy_*_user, copy_page, memcpy, memset. # These are much faster. clear/copy_page don't force the new page out # of memory now which should speed up user processes. Also full # workaround for errata #91. # - Some cleanup in pageattr.c code. # - Fix warning in i387.h # - Fix wrong PAGE_KERNEL_LARGE define. This fixes a security hole and # makes AGP work again. # - Fix wrong segment exception handler to not crash. # - Fix incorrect swapgs handling in bad iret exception handling # - Clean up some boot printks # - Micro optimize exception handling preamble. # - New reboot handling. Supports warm reboot and BIOS reboot vector # reboot now. # - (2.4) Use MTRRs by default in vesafb # - Fix bug in put_dirty_page: use correct page permissions for the stack # - Fix type of si_band in asm-generic/siginfo.h to match POSIX/glibc # (needs checking with other architecture maintainers) # - (2.4) Define ARCH_HAS_NMI_WATCHDOG # - Minor cleanup in calling.h # - IOMMU tuning: only flush the GART TLB when the IOMMU aperture area # allocation wraps. Also don't clear entries until needed. This # should increase IO performance for IOMMU devices greatly. Still a # bit experimental, handle with care. # - Unmap the IOMMU aperture from kernel mapping to prevent unwanted CPU # prefetches. # - Make IOMMU_LEAK_TRACE depend on IOMMU_DEBUG # - Fix minor bug in pci_alloc_consistent - always check against the dma # mask of the device, not 0xffffffff. # - Remove streamining mapping delayed flush in IOMMU: not needed anymore # and didn't work correctly in 2.5 anyways. # - Fix the bad pte warnings caused by the SMP/APIC bootup. # - Forward port 2.4 fix: ioperm was changing the wrong io ports in some # cases. # - Minor cleanups # - Some cleanups in pageattr.c (still buggy) # - Fix some bugs in the AGP driver. # - Forward port from 2.4: mask all reserved bits in debug register in # ptrace. Previously gdb could crash the kernel by passing invalid # values. # - Security fix: make sure FPU is in a defined state after an # FXSAVE/FXRSTOR exception occurred. # - Eats keys on panic (works around a buggy KVM) # - Make user.h user includeable. # - Disable sign compare warnings for gcc 3.3-hammer # - Use DSO for 32bit vsyscalls and dump it in core dumps. Add dwarf2 # information for the vsyscalls. # Thanks to Richard Henderson for helping me with the nasty parts of # it. I had to do some changes over his patch and it's currently only # lightly tested. Handle with care. This only affects 32bit programs # that use a glibc 3.2 with sysenter support. # - Security fixes for the 32bit ioctl handlers. Also some simplications # and speedups. # - gcc 3.3-hammer compile fixes for inline assembly # - Remove acpi.c file corpse. # - Lots of warning fixes # - Disable some Dprintks to make the bootup quieter again # - Clean up ptrace a bit (together with warning fixes) # - Merge with i386 (handle ACPI dynamic irq entries properly) # - Disable change_page_attr in pci-gart for now. Strictly that's # incorrect, need to do more testing for the root cause of the current # IOMMU problems. # - Update defconfig # - Disable first prefetch in copy_user that is likely to trigger Opteron # Errata #91 # - More irqreturn_t fixes # - Add pte_user and fix the vsyscall ptrace hack in generic code. # It's still partly broken # - Port verbose MCE handler from 2.4 # -------------------------------------------- # 03/05/23 greg@kroah.com 1.1215.2.1 # Merge kroah.com:/home/greg/linux/BK/bleed-2.5 # into kroah.com:/home/greg/linux/BK/gregkh-2.5 # -------------------------------------------- # 03/05/23 david-b@pacbell.net 1.1215.2.2 # [PATCH] USB: bugfix endpoint state # # This resolves some problems in the endpoint disable # patch I sent recently: # # - wasn't un-halting some endpoints # - was clobbering ep0 setup in some cases. # -------------------------------------------- # 03/05/23 baldrick@wanadoo.fr 1.1215.2.3 # [PATCH] USB speedtouch: set owner fields # # I think I'd better work on my plausible deniability... # -------------------------------------------- # 03/05/23 stern@rowland.harvard.edu 1.1215.2.4 # [PATCH] USB: uhci Interrupt Latency fix # # Paul: # # Okay, I think this patch ought to do the trick.

This turned out to be an Owner ID allocation issue where a # called method did not get a new ID assigned to it. Eventually, (after 64k calls), the # Owner ID UINT16 would wraparound so that the ID would be the same as the caller's and the # called method would delete the caller's namespace. # # Implemented extended error reporting for control methods that are aborted due to a # run-time exception. Output includes the exact AML instruction that caused the method # abort, a dump of the method locals and arguments at the time of the abort, and a trace of # all nested control method calls. # # Modified the interpreter to allow the creation of buffers of zero length from the AML # code. Implemented new code to ensure that no attempt is made to actually allocate a # memory buffer (of length zero), only a buffer object with a NULL buffer pointer and # length zero. A warning is no longer issued when the AML attempts to create a zero-length # buffer. # # Implemented a workaround for the "leading asterisk problem" in _HIDs, _UIDs, and _CIDs. # One leading asterisk is automatically removed if present in all HID, UID, and CID # strings. # # Implemented full support for _CID methods that return a package of multiple CIDs. The # AcpiGetObjectInfo interface now returns a device _HID, _UID, and _CID list if present. # This required a change to the external interface to pass an ACPI_BUFFER object as a # parameter, since the _CID list is of variable length. # # Fixed a problem with the new AE_SAME_HANDLER exception where handler initialization code # did not know about this exception. # -------------------------------------------- # 03/05/23 agrover@groveronline.com 1.1215.1.6 # ACPI: Allow multiple compatible IDs for PnP purposes # -------------------------------------------- # 03/05/24 paulus@samba.org 1.1217 # Merge samba.org:/stuff/paulus/kernel/linux-2.5 # into samba.org:/stuff/paulus/kernel/for-linus-ppc # -------------------------------------------- # 03/05/23 B.Zolnierkiewicz@elka.pw.edu.pl 1.1215.3.1 # [PATCH] Fix incorrect enablebits for all AMD and nVidia IDE chipsets. # # Fix incorrect enablebits for all AMD and nVidia IDE chipsets. # Author: Vojtech Pavlik # -------------------------------------------- # 03/05/23 B.Zolnierkiewicz@elka.pw.edu.pl 1.1215.3.2 # [PATCH] Add IDE support for VIA vt8237 southbridge. # # Add IDE support for VIA vt8237 southbridge. # Author: Vojtech Pavlik # -------------------------------------------- # 03/05/23 B.Zolnierkiewicz@elka.pw.edu.pl 1.1215.3.3 # [PATCH] Intel ICH5 basic SATA support # # Add Intel ICH5 basic SATA support (from 2.4 by Andre Hedrick) # and as a bonus kill duplicate entry in piix_pci_info[]. # -------------------------------------------- # 03/05/23 B.Zolnierkiewicz@elka.pw.edu.pl 1.1215.3.4 # [PATCH] misc AMD IDE driver fixes # # Fix incorrect UDMA100 cable test (by Dave Jones). # Fix compilation warning. # -------------------------------------------- # 03/05/23 B.Zolnierkiewicz@elka.pw.edu.pl 1.1215.3.5 # [PATCH] add hwif->hold flag # # Add hwif->hold flag for hotswap interfaces. # Initialize founded hwif in ide_register_hw(). # # Original patch by Benjamin Herrenschmidt. # -------------------------------------------- # 03/05/23 B.Zolnierkiewicz@elka.pw.edu.pl 1.1215.3.6 # [PATCH] SiS IDE driver fixes # # SiS IDE driver fixes by Lionel Bouton: # -

(JSG) - * 12/03/00 - Created pool of request packet structures for use in sending out sbp2 command - * and agent reset requests. This removes the kmallocs/kfrees in the critical I/O paths, - * and also deals with some subtle race conditions related to allocating and freeing - * packets. (JSG) - * 12/09/00 - Improved the sbp2 device detection by actually reading the root and unit - * directory (khk@khk.net) - * 12/23/00 - Following changes/enhancements were made (JSG) - * * Only do SCSI to RBC command conversion for Direct Access and Simplified - * Direct Access Devices (this is pulled from the config rom root directory). - * This is needed because doing the conversion for all device types broke the - * Epson scanner. Still looking for a better way of determining when to convert - * commands (for RBC devices). Thanks to khk for helping on this! - * * Added ability to "emulate" physical dma support, for host adapters such as TILynx. - * * Determine max payload and speed by also looking at the host adapter's max_rec field. - * 01/19/01 - Added checks to sbp2 login and made the login time-out longer. Also fixed a compile - * problem for 2.4.0. (JSG) - * 01/24/01 - Fixed problem when individual s/g elements are 64KB or larger. Needed to break - * up these larger elements, since the sbp2 page table element size is only 16 bits. (JSG) - * 01/29/01 - Minor byteswap fix for login response (used for reconnect and log out). - * 03/07/01 - Following changes/enhancements were made (JSG) - * * Changes to allow us to catch the initial scsi bus scan (for detecting sbp2 - * devices when first loading sbp2.o). To disable this, un-define - * SBP2_SUPPORT_INITIAL_BUS_SCAN. - * * Temporary fix to deal with many sbp2 devices that do not support individual - * transfers of greater than 128KB in size. - * * Mode sense conversion from 6 byte to 10 byte versions for CDRW/DVD devices. (Mark Burton) - * * Define allowing support for goofy sbp2 devices that do not support mode - * sense command at all, allowing them to be mounted rw (such as 1394 memory - * stick and compact flash readers). Define SBP2_MODE_SENSE_WRITE_PROTECT_HACK - * if you need this fix. - * 03/29/01 - Major performance enhancements and misc. other changes. Thanks to Daniel Berlin for many of - * changes and suggestions for change: - * * Now use sbp2 doorbell and link commands on the fly (instead of serializing requests) - * * Removed all bit fields in an attempt to run on PPC machines (still needs a little more work) - * * Added large request break-up/linking support for sbp2 chipsets that do not support transfers - * greater than 128KB in size. - * * Bumped up max commands per lun to two, and max total outstanding commands to eight. - * 04/03/01 - Minor clean-up. Write orb pointer directly if no outstanding commands (saves one 1394 bus - * transaction). Added module load options (bus scan, mode sense hack, max speed, serialize_io, - * no_large_transfers). Better bus reset handling while I/O pending. Set serialize_io to 1 by - * default (debugging of deserialized I/O in progress). - * 04/04/01 - Added workaround for PPC Pismo firewire chipset. See #define below. (Daniel Berlin) - * 04/20/01 - Minor clean-up. Allocate more orb structures when running with sbp2 target chipsets with - * 128KB max transfer limit. - * 06/16/01 - Converted DMA interfaces to pci_dma - Ben Collins - * - * - * 11/17/01 - Various bugfixes/cleanups: - * * Remember to logout of device in sbp2_disconnect. - * * If we fail to reconnect to a device after bus reset - * remember to release unit directory, so the ieee1394 - * knows we no longer manage it. - * * Unregister scsi hosts in sbp2_remove_host when a - * hpsb_host goes away. - * * Remove stupid hack in sbp2_remove_host. - * * Switched to "manual" module initialization - * (i.e. not scsi_module.c) and moved sbp2_cleanup - * moved sbp2scsi_release to sbp2_module_ext. The - * release function is called once pr. registered - * scsi host, but sbp2_cleanup should only be called - * upon module unload. Moved much initialization - * from sbp2scsi_detect to sbp2_module_init. - * Kristian Hogsberg - * 01/06/02 - Misc bug fixes/enhancements: (JSG) - * * Enable use_new_eh_code for scsi stuff. - * * Do not write all ones for NULL ORB high/low fields, but - * rather leave reserved areas zeroed (per SBP2 spec). - * * Use newer scsi transfer direction passed down instead of our - * direction table. - * * Bumped login time-out to 20 seconds, as some devices are slow. - * * Fixed a couple scsi unregister bugs on module unload - * 01/13/02 - Fixed compatibility with certain SBP2 devices, such as Iomega - * 1394 devices (Peerless, Jazz). Also a bit of clean-up of the - * driver, thanks to H.J.Lu (hjl@lucon.org). Removed mode_sense_hack - * module load option, as it's been fixed in the 2.4 scsi stack. - * 02/10/02 - Added support for max_sectors, minor fix for inquiry command, make - * up sbp2 device type from inquiry response data if not part of - * device's 1394 unit directory. (JSG) - * 02/18/02 - Code clean-up and enhancements: (JSG) - * * Finish cleaning out hacked code for dealing with broken sbp2 devices - * which do not support requests of 128KB or greater. Now use - * max_sectors scsi host entry to limit transfer sizes. - * * Change status fifo address from a single address to a set of addresses, - * with each sbp2 device having its own status fifo address. This makes - * it easier to match the status write to the sbp2 device instance. - * * Minor change to use lun when logging into sbp2 devices. First step in - * supporting multi-lun devices such as CD/DVD changer devices. - * * Added a new module load option for setting max sectors. For use by folk - * who'd like to bump up the max scsi transfer size supported. - * * Enabled deserialized operation by default, allowing for better performance, - * particularily when running with multiple sbp2 devices. For debugging, - * you may enable serialization through use of the sbp2_serialize_io module - * load option (e.g. insmod sbp2 sbp2_serialize_io=1). - * 02/20/02 - Added a couple additional module load options. - * Needed to bump down max commands per lun because of the !%@&*^# QPS CDRW - * drive I have, which doesn't seem to get along with other sbp2 devices - * (or handle linked commands well). - * 04/21/02 - Added some additional debug capabilities: - * * Able to handle phys dma requests directly, if host controller has phys - * dma disabled (e.g. insmod ohci1394 phys_dma=0). Undefine CONFIG_IEEE1394_SBP2_PHYS_DMA - * if you'd like to disable sbp2 driver from registering for phys address range. - * * New packet dump debug define (CONFIG_IEEE1394_SBP2_PACKET_DUMP) which allows - * dumping of all sbp2 related packets sent and received. Especially effective - * when phys dma is disabled on ohci controller (e.g. insmod ohci1394 phys_dma=0). - * * Added new sbp2 module load option (exclusive_login) for allowing - * non-exclusive login to sbp2 device, for special multi-host applications. - * 04/23/02 - Fix for Sony CD-ROM drives. Only send fetch agent reset to sbp2 device if it - * returns the dead bit in status. Thanks to Chandan (chandan@toad.net) for this one. - * 04/27/02 - Fix sbp2 login problem on SMP systems, enable real spinlocks by default. (JSG) - * 06/09/02 - Don't force 36-byte SCSI inquiry, but leave in a define for badly behaved devices. (JSG) - * 02/04/03 - Fixed a SMP deadlock (don't hold sbp2_command_lock while calling sbp2scsi_complete_command). - * Also save/restore irq flags in sbp2scsi_complete_command - Sancho Dauskardt - * 02/06/03 - Removed spinlock debugging; use kernel stuff instead (sda) - * 02/10/03 - Adopt to new hot-plug aware SCSI inferface (hch@lst.de) - * - */ - - -/* - * Includes */ #include @@ -295,7 +79,7 @@ #include "sbp2.h" static char version[] __devinitdata = - "$Rev: 919 $ James Goodwin "; + "$Rev: 931 $ Ben Collins "; /* * Module load parameter definitions @@ -829,65 +613,81 @@ if (!hi) return -ENODEV; - return sbp2_start_device(hi, ud); + return sbp2_start_ud(hi, ud); } static int sbp2_remove(struct device *dev) { + struct scsi_id_group *scsi_group; + struct list_head *lh, *next; struct unit_directory *ud; struct scsi_id_instance_data *scsi_id; SBP2_DEBUG(__FUNCTION__); ud = container_of(dev, struct unit_directory, device); - scsi_id = ud->device.driver_data; + scsi_group = ud->device.driver_data; ud->device.driver_data = NULL; - if (scsi_id != NULL) { - sbp2_logout_device(scsi_id); - sbp2_remove_device(scsi_id); + list_for_each_safe (lh, next, &scsi_group->scsi_id_list) { + scsi_id = list_entry(lh, struct scsi_id_instance_data, list); + + if (scsi_id != NULL) { + sbp2_logout_device(scsi_id); + sbp2_remove_device(scsi_id); + } } + kfree(scsi_group); + return 0; } static void sbp2_update(struct unit_directory *ud) { - struct scsi_id_instance_data *scsi_id = ud->device.driver_data; - struct sbp2scsi_host_info *hi = scsi_id->hi; + struct sbp2scsi_host_info *hi; + struct scsi_id_group *scsi_group = ud->device.driver_data; + struct list_head *lh, *next; + struct scsi_id_instance_data *scsi_id; unsigned long flags; SBP2_DEBUG("sbp2_update"); - if (sbp2_reconnect_device(scsi_id)) { + list_for_each_safe (lh, next, &scsi_group->scsi_id_list) { + scsi_id = list_entry(lh, struct scsi_id_instance_data, list); + + hi = scsi_id->hi; + + if (sbp2_reconnect_device(scsi_id)) { - /* - * Ok, reconnect has failed.

It's + useful for testing, and is also a working example showing how + USB "gadget drivers" can be written. + + Make this be the first driver you try using on top of any new + USB peripheral controller driver. Then you can use host-side + test software, like the "usbtest" driver, to put your hardware + and its driver through a basic set of functional tests. + + Gadget Zero also works with the host-side "usb-skeleton" driver, + and with many kinds of host-side test software. You may need + to tweak product and vendor IDs before host software knows about + this device, and arrange to select an appropriate configuration. + + Say "y" to link the driver statically, or "m" to build a + dynamically linked module called "g_zero". + +config USB_ZERO_NET2280 + bool + # for now, treat the "dummy" hcd as if it were a net2280 + depends on USB_ZERO && (USB_NET2280 || USB_DUMMY_HCD) + default y + +config USB_ZERO_PXA250 + bool + depends on USB_ZERO && USB_PXA250 + default y + +config USB_ZERO_SA1100 + bool + depends on USB_ZERO && USB_SA1100 + default y + + +config USB_ETH + tristate "Ethernet Gadget" + depends on USB_GADGET && (USB_DUMMY_HCD || USB_NET2280 || USB_PXA250 || USB_SA1100) + help + This driver implements the "Communication Device Class" (CDC) + Ethernet Control Model.
