The attached patch adds support for using cpuid(4) instead of cpuid(2), to
get CPU cache information in a deterministic way for Intel CPUs, whenever
supported. The details of cpuid(4) can be found here
IA-32 Intel Architecture Software Developer's Manual (vol 2a)
(http://developer.intel.com/design/pentium4/manuals/index_new.htm#sdm_vol2a)
and
Prescott New Instructions (PNI) Technology: Software Developer's Guide
(http://www.intel.com/cd/ids/developer/asmo-na/eng/events/43988.htm)
The advantage of using the cpuid(4) ('Deterministic Cache Parameters Leaf') are:
- It provides more information than the descriptors provided by cpuid(2)
- It is not table based as cpuid(2). So, we will not need changes to the
kernel to support new cache descriptors in the descriptor table (as is
the case with cpuid(2)).
The patch also adds a bunch of interfaces under
/sys/devices/system/cpu/cpuX/cache, showing various information about the
caches. Most useful field being shared_cpu_map, which says what caches are
shared among which logical cpus.
The patch adds support for both i386 and x86-64.

The existing x86-64 kprobes implementation doesn't cope with the
%RIP-relative addressing mode. Kprobes work by single-stepping a copy of
an instruction overwritten by a breakpoint. When a probe is inserted on an
instruction that uses the %RIP-relative data addressing mode, the copy run
in a different location gets different data and so the presence of that
probe causes the probed code to read or write the wrong memory location.
Without this problem fixed, it is woefully unsafe to use the current
kprobes code on x86-64 unless you are sure the instruction you instrument
is not one that accesses global data using the %RIP addressing mode.
This patch fixes the problem by recognizing the %RIP-relative addressing
mode in an instruction when it's being copied to insert the kprobe, and
adjusting its displacement so that it finds the right data. Taking this
approach requires that the copied instruction's %RIP value be within 2GB of
the virtual address of the data, i.e. the text/data areas of the kernel
code and loaded modules. To satisfy this need the patch also replaces the
use of vmalloc for getting instruction pages with lower-level calls to use
a different part of the address space, the area at the top of the address
space just above where modules are loaded. I left one page of red zone at
the top, and the 1MB-4KB thus available allows for at most 69632 kprobes.
(If we ever need to overcome that limit, we can change this to add a hook
into the arch/x86_64/kernel/modules.c code and allocate pages inside the
module area loading area instead.)

Andi noted that during normal runtime cpu_idle_map is bounced around a lot,
and occassionally at a higher frequency than the timer interrupt wakeup
which we normally exit pm_idle from. So switch to a percpu variable.
I didn't move things to the slow path because it would involve adding
scheduler code to wakeup the idle thread on the cpus we're waiting for.

This patch avoids a lockup with kernel.panic sysctl > 0, due an underflow
of the number of the cpus.
Later, Andrea said:
While this still seems a needed fix, unfortunately this wasn't enough to
fix the problem (the first positive report I got was because they did a
mistake and they tested an UP kernel, oh well ;).
Anyway the smp_stop_cpu executed by the cpu that invoked panic is wrong
and it really causes an underflow of the number of cpus that can lead to
further lockups. So I don't want to stop you from merging it since it
seems a correct fix and it brings x86-64 in line with the x86 code too.
But apparently we need something more than this too.

This patch adds the mem=X boot command line option for PPC64.
On iSeries the user's mem=X value is aligned to PAGE_SIZE, on pSeries we
align to 16 MB which is the size of a large page.
The iSeries implementation is fairly straight forward, we declare mem=X as
an early_param() and then in iSeries_init_early() we modify the
systemcfg->physicalMemorySize based on that value.
On pSeries the mem=X option is parsed in prom_init.c before the kernel
proper starts, and is used to modify prom_init_mem()'s idea of memory. The
mem=X value and computed tce_alloc_start/end values are saved by
prom_init() into the device tree for later use by the kernel.
The device tree properties are read by the kernel in
early_dt_scan_chosen(), and used to modify the lmb structure in
early_init_devtree(). That's the guts of it.
On non-LPAR machines the tce_alloc_start/end values are read from the
device tree and used in htab_initialize() to make sure the TCE table is
mapped at the real top of RAM.
If NUMA is enabled we also have to make changes in parse_numa_properties()
and do_init_bootmem() to exclude memory regions above the memory limit, and
truncate any region which stradles the limit.
NB. This patch does not facilitate using mem=X to give drivers access to
large regions of contiguous memory.

This patch against 12-rc1 adds seccomp to the ppc64 arch. I tested it
successfully with the seccomp_test. I didn't bother to change the syscall
exit not to check for TIF_SECCOMP, in theory that bit could be optimized
but it's an optimization in the slow path, and current code is a bit
simpler. I also verified it still compiles and works fine on x86 and
x86-64.
Instead of the TIF_32BIT redefine, if you want to change x86-64 to use
TIF_32BIT too (instead of TIF_IA32), let me know.

I've seen that MPC8555 support also made it into linux-2.6 by now.
I don't have hardware and time to test, but it looks like this bug has made
it over from the linuxppc-2.4 tree. The 8541/8555 has a smaller CPM DPRAM
than the standard CPM2, just like the 8272.
Unfortunately, the manual recommends you to use a segment of CPM DPRAM that
is not implemented in the 8541/55. If the smaller DPRAM is not taken into
account, fcc_enet.c will initialise the internal CPM buffer pointers
(fcc_riptr/fcc_tiptr) to invalid offsets, with the result that all the FCC
will ever send and receive are 0xff-en.

This patch applies on top of my patch of March 26, entitled "cpusets
special case GFP_ATOMIC allocs". It tones down my panic'y commentary.
My commentary shouldn't imply that failed GFP_ATOMICs should lead to, or
normally lead to, panics. Even though there are a few panic() calls
following failed GFP_ATOMIC allocs, this is not the usual or desired result
of a failed GFP_ATOMIC. The kernel will probably drop some detail on the
floor and keep on working.
Thanks to Nick Piggin for noticing (I hope this answers his point.)

The attached patch replaces backing_dev_info::memory_backed with capabilitied
bitmap. The capabilities available include:
(*) BDI_CAP_NO_ACCT_DIRTY
Set if the pages associated with this backing device should not be
tracked by the dirty page accounting.
(*) BDI_CAP_NO_WRITEBACK
Set if dirty pages associated with this backing device should not have
writepage() or writepages() invoked upon them to clean them.
(*) Capability markers that indicate what a backing device is capable of
with regard to memory mapping facilities. These flags indicate whether a
device can be mapped directly, whether it can be copied for a mapping,
and whether direct mappings can be read, written and/or executed. This
information is primarily aimed at improving no-MMU private mapping
support.
The patch also provides convenience functions for determining the dirty-page
capabilities available on backing devices directly or on the backing devices
associated with a mapping. These are provided to keep line length down when
checking for the capabilities.

From: "HARDY, Steven" <steven.hardy@astrium.eads.net>
I have found a bug in the pcnet32 driver (drivers/net/pcnet32.c)
affecting all ethernet cards based on the AMD79C975 chip, using the
fiber interface.
It's a one line fix, where some config registers get corrupted during
initialisation (which stops the Fiber interface working with this chip)
This bug was introduced somewhere betweeen 2.4.17 and 2.6.x (noticed
whilst upgrading to 2.6), and it may affect other chips too. I have
checked all versions up to 2.6.11-bk6 and they are all broken.

1. Change of Copyright to reflect S2io's new name "Neterion Inc."
2. Updated driver version number.
3. Add an additional PCI device id to support Neterion's new Xframe II.
Some background info on Xframe-II, just in case -
The NIC was announced back in January (see
http://www.serverwatch.com/news/article.php/3464871)
Xframe II is a PCI-X 2.0 DDR adapter designed to work in PCI-X 2.0 servers
(it is also backwards compatible with current pci-x and pci slots); it's a
first card to overcome pci-x 133 throughput bottleneck. Some of these pci-x
2.0 servers are available now and more are coming later in the year.
Xframe II is completely backward compatible and hence the current driver
will work as-is, except the device id change.
There are some additional features/stateless offloads in Xframe-II
as well; we plan to submit patches for these soon.

In netlink_dump we're operating on sk after dropping the cb lock.
This is racy because the owner of the socket could close it after
we drop the cb lock.
This is possible because netlink_dump isn't always called from the
context of the process that owns the socket. For instance, if there
is contention on rtnl then rtnetlink requests will be processed by
the process that owns the rtnl.
The solution is to hold a ref count on the socket before we drop
the cb lock.

There is no 'ports' parameter for the ip_nat_ftp and ip_nat_irc modules in
2.6.11: the ports parameter supplied to the
ip_conntrack_ftp/ip_conntrack_irc module defines the ports. It was
unfortunate that we were lazy in the original implementation, and forced
the user to duplicate the arguments.
Even more unfortunate, the removal of the parameter caused autoloading to
break for various setups, with an 'Unknown parameter' message. The
solution is to restore the parameter as a dummy, with a polite warning
message that it is no longer neccessary.

When a device is being torn down (mostly in USB ejection)
we hit conditions where SCSI hangs in wait_for_completion().
The reason is that the scsi request prep function does a
state check on the device and rejects it with BLKPREP_KILL if
we're in the DEL (going away, no more I/O) state.
Unfortunately, I/O submitted by scsi_wait_req() doesn't have
its request->end_io initialised, so we're never notified of
this (the submit path expects everything to come back via
the scsi_request->sr_done() routine, which only happens
if the I/O actually gets submitted.
Note: almost everything that uses scsi_do_request() is wrong

This fixes the TLB miss mapping cache flush function.
The flush was attempting to invalidate the coverage start virtual addresses
for the cached page table mappings held in registers SCR0 and SCR1 by writing
0 into them. Unfortunately, 0x00000000-0x04000000 is itself a valid part of
the virtual address range. This patches places -1 in there instead, thus
specifying 0xfc000000-0xffffffff which is covered by a static I/O mapping, and
so shouldn't ever be seen by the TLB-miss handler.

This fixes a problem that cropped up resuming OHCI from PCI D3 on
NForce2. Evidently the register controlling frame timing gets
clobbered in D3, but not other registers ... a "by the book" reinit
seems to solve this particular problem. (And ought to help a few
startup glitches on other implementations. Linux never used that
toggle bit before, and has had to struggle with glitchy init...)
It also updates some diagnostics to be bit more useful, and tries
to avoid a particular "wakeup while suspending" glitch that seems
particular to one particular type of Australian mouse.

This patch against 2.6.10 provides the driver for the CP2101 and CP2102
USB to RS232 adaptor chips which are found in some serial converter
cables and usb mobile phone cables.
It provides cp2101.c, and patches Kconfig and Makefile in
drivers/usb/serial Since there is no technical data sheet freely
available for these chips, much of the code in this driver has been
based on protocol analysis, assumptions and guesswork.
The cp210x family of devices have OEM programmable device IDs so updates
will be required as and when new devices are found.
The driver currently only supports configuration of baud rate, data
bits, stop bits and parity mode. While this is enough to enable the use
of a wide range of devices based on this chip, the driver is still
incomplete in many areas such as flow control. Unfortunately without
technical datasheets, implementing these features is made very difficult
indeed.

According to this article http://lwn.net/Articles/125930/, "When
cancel_delayed_work() returns zero, it means that the delayed
work request was fired off before the call; it might, in fact,
be running on another CPU when the cancel attempt is made".
If it is successful, it returns a nonzero value. Tracing
through cancel_delayed_work's timer usage would seem to confirm
this. The fc class today though performs a flush_scheduled_work,
when the return value is nonzero instead of zero.
Also it appears the fc class will use flush_scheduled_work to
flush the work from the shost_work_q when it should be using
flush_workqueue(shost->work_q) (flush_scheduled_work() only
flushes the default, keventd_wq, work queue).
The attached patch adds a scsi_flush_work function for
scsi_transport_fc to use and it fixes the cancel_delayed_work()
test to detect when to flush the work queues correctly (it
also only calls cancel_delayed_work when the work is queued
as delayed (scan_work is not delayed).

Fixing the interrupt tst for CONFIG_PREEMPT on x86-64 exposes another
bug with CONFIG_PREEMPT_BKL. Calling schedule due to preemption
releases the BKL which it shouldn't do.
Call preempt_schedule_irq instead (like for i386). This fixes the
easily reproducible filesystem errors I've seen (with reiserfs, which

It turns out that a bunch of USB-IDE converters make the mistake of
returning SK = 04 (Hardware Error) whenever the IDE device signals any
sort of error, without bothering to distinguish recoverable from
non-recoverable errors. The best way to handle this is for usb-storage to
set a per-device flag indicating that these errors should always be
retried. The current scheme (blacklist flag but no per-device flag) isn't
well suited for this situation.
This patch adds the per-device flag and sets it initially based on the
blacklist setting. Once this has been merged, a separate patch will be
submitted to Matt Dharm adding the corresponding support to usb-storage.

We missed flushing the TLB when we're unmapping only reserved pages.
Since the kernel is now better at passing vmas which correspond
solely with the region to unmap, we can use tlb_*_vma() to do
"just enough" flushing, both for the TLB and cache.
We can avoid all flushes in tlb_*_vma() for the full-MM case, and
just do a flush_tlb_mm(). We can omit the cache flushing because
this thread will die soon.

There is a race condition in jbd between journal_unmap_buffer() and
journal_commit_transaction(). This is leading to corruption of buffers on the
transaction's t_locked_list, leading to a variety of symptoms usually
involving an oops in kjournald.
The problem is that various special-case exit paths in journal_unmap_buffer()
call journal_put_journal_head without any locking. This is racing against a
refiling of the same journal_head in journal_commit_transaction():
__journal_unfile_buffer(jh);
__journal_file_buffer(jh, commit_transaction,
BJ_Locked);
The way these functions work, this leaves the jh temporarily with
b_transaction==NULL; and if journal_unmap_buffer()'s call to
journal_put_journal_head() hits this window, it sees the NULL transaction and
frees the journal_head which is just about to get refiled on the locked list.
The main exit path on journal_unmap_buffer() performs its
journal_put_journal_head() before dropping the j_list_lock, so is not
vulnerable to this race. The fix is to move the other similar calls on
special-case exit branches in that function so that they also release the
journal_head before dropping that lock.
This is low-risk since the new order has already been tested as the normal
exit path from this function. The change has had extensive testing and has
been shown to fix the problem with no regressions found.

Fix destruction of in-use journal_head
journal_put_journal_head() can destroy a journal_head at any time as
long as the jh's b_jcount is zero and b_transaction is NULL. It has no
locking protection against the rest of the journaling code, as the lock
it uses to protect b_jcount and bh->b_private is not used elsewhere in
jbd.
However, there are small windows where b_transaction is getting set
temporarily to NULL during normal operations; typically this is
happening in
__journal_unfile_buffer(jh);
__journal_file_buffer(jh, ...);
call pairs, as __journal_unfile_buffer() will set b_transaction to NULL
and __journal_file_buffer() re-sets it afterwards. A truncate running
in parallel can lead to journal_unmap_buffer() destroying the jh if it
occurs between these two calls.
Fix this by adding a variant of __journal_unfile_buffer() which is only
used for these temporary jh unlinks, and which leaves the b_transaction
field intact so that we never leave a window open where b_transaction is
NULL.
Additionally, trap this error if it does occur, by checking against
jh->b_jlist being non-null when we destroy a jh.

Janitoring - error handling during attach
o av7110_arm_sync(): small helper to factor out some code;
o av7110_attach() does not check the status code returned by all the
functions is uses;
o balance the error path in av7110_attach and have it easy to check.
Please check it;
o if everything is correctly balanced, device_initialized is not needed
anymore in struct av7110;
o av7110_detach(): no need to cast a void * pointer;
o av7110_detach(): die #ifdef, die !
o change the returned value of av7110_av_exit() as it can't fail;
o change the returned value of av7110_ca_init() as it can fail. Removed
extraneous casts while are it;
o check for failure of vmalloc() in ci_ll_init().
o vfree(NULL) is safe.
