This makes 64-bit ptrace calls setting the 64-bit orig_ax field for a
32-bit task sign-extend the low 32 bits up to 64. This matches what a
64-bit debugger expects when tracing a 32-bit task.
This follows on my "x86_64 ia32 syscall restart fix". This didn't
matter until that was fixed.
The debugger ignores or zeros the high half of every register slot it
sets (including the orig_rax pseudo-register) uniformly. It expects
that the setting of the low 32 bits always has the same meaning as a
32-bit debugger setting those same 32 bits with native 32-bit
facilities.
This never arose before because the syscall restart check never
matched any -ERESTART* values due to lack of sign extension. Before
that fix, even 32-bit ptrace setting orig_eax to -1 failed to trigger
the restart check anyway. So this was never noticed as a regression
of 64-bit debuggers vs 32-bit debuggers on the same 64-bit kernel.

[ Changed to just do the sign-extension unconditionally on x86-64,
since orig_ax is always just a small integer and doesn't need
the full 64-bit range ]

As long as the directory contents haven't changed, we should just let the
path walk proceed to cross the mountpoint. Apart from being an optimisation
in the case of 'nohide' mountpoint traversals, it also fixes an issue with
referrals: referral inodes don't have valid filehandles, so calling
nfs_revalidate_inode() on them is a bug.

When we detect that we've crossed a mountpoint on the remote server, we
must take care not to use that inode to revalidate the fsid on our
current superblock. To do so, we label the inode as a remote mountpoint,
and check for that in nfs_update_inode().

The card state mutex was only initialized when a device was connected,
but used during unload unconditionally, leading to an Oops if a driver
was loaded and unloaded again without ever connecting a device.
Fix this by initializing the mutex as soon as the structure is allocated.
Also add a missing mutex unlock revealed in the same execution path.
This fixes a possible Oops in 2.6.25-rc that was introduced by commit
e468c04894f36045cf93d1384183a461014b6840 ("Gigaset: permit module

randconfig testing found a bootup lockup in drivers/char/esp.c because

Sripathi Kodi reported a crash in the -rt kernel:
https://bugzilla.redhat.com/show_bug.cgi?id=435674
this is due to a place that can reschedule a task without holding
the tasks runqueue lock. This was caused by the RT balancing code
that pulls RT tasks to the current run queue and will reschedule the
current task.
There's a slight chance that the pulling of the RT tasks will release
the current runqueue's lock and retake it (in the double_lock_balance).
During this time that the runqueue is released, the current task can
migrate to another runqueue.
In the prio_changed_rt code, after the pull, if the current task is of
lesser priority than one of the RT tasks pulled, resched_task is called
on the current task. If the current task had migrated in that small
window, resched_task will be called without holding the runqueue lock
for the runqueue that the task is on.
This race condition also exists in the mainline kernel and this patch
adds a check to make sure the task hasn't migrated before calling
resched_task.

The new x86 setup code (4fd06960f120) broke booting on an old P3/500MHz
with an onboard Voodoo3 of mine. After debugging it, it turned out
to be caused by the fact that the vesa probing now asks for VBE2 data.
Disassembing the video BIOS shows that it overflows the vesa_general_info
structure when VBE2 data is requested because the source addresses for the
information strings which get strcpy'ed to the buffer lie outside the 32K
BIOS code (and hence contain long sequences of 0xff's).

The old setup code didn't ask for VBE2 info, and the new code doesn't

convert_fxsr_to_user() in 2.6.24's i387_32.c did this, and
convert_to_fxsr() also does the inverse, so I assume it's an oversight
that it is no longer being done.
[ mingo@elte.hu:
we encode it this way because there's no space for the 'FPU Last
Instruction Opcode' (->fop) field in the legacy user_i387_ia32_struct
that PTRACE_GETFPREGS/PTRACE_SETFPREGS uses.
it's probably pure legacy - i'd be surprised if any user-space relied on
the FPU Last Opcode in any way. But indeed we used to do it previously
so the most conservative thing is to preserve that piece of information.

The Linux kernel currently does not clear the direction flag before
calling a signal handler, whereas the x86/x86-64 ABI requires that.
Linux had this behavior/bug forever, but this becomes a real problem
with gcc version 4.3, which assumes that the direction flag is
correctly cleared at the entry of a function.
This patches changes the setup_frame() functions to clear the
direction before entering the signal handler.

NUMA slab allocator cpu migration bugfix
The NUMA slab allocator (specifically, cache_alloc_refill)
is not refreshing its local copies of what cpu and what
numa node it is on, when it drops and reacquires the irq
block that it inherited from its caller. As a result
those values become invalid if an attempt to migrate the
process to another numa node occured while the irq block
had been dropped.
The solution is to make cache_alloc_refill reload these
variables whenever it drops and reacquires the irq block.
The error is very difficult to hit. When it does occur,
one gets the following oops + stack traceback bits in
check_spinlock_acquired:
kernel BUG at mm/slab.c:2417

kmem_cache_alloc+0xd0

SLUB should pack even small objects nicely into cachelines if that is what
has been asked for. Use the same algorithm as SLAB for this.
The effect of this patch for a system with a cacheline size of 64
bytes is that the 24 byte sized slab caches will now put exactly
2 objects into a cacheline instead of 3 with some overlap into
the next cacheline. This reduces the object density in a 4k slab
from 170 to 128 objects (same as SLAB).

When EFI_DEBUG is defined to a non-zero value in arch/ia64/kernel/efi.c,
the efi memory regions are displayed. This patch enhances the
display code in a few ways:
1. Use TB, GB and MB as well as KB as units.
Although this introduces rounding errors (KB doesn't as
size is always a multiple of 4Kb), it does make
things a lot more readable.
Also as the range is also shown, it is possible to note the exact size
if it is important. In my experience, the size field is mostly useful
for getting a general idea of the size of a region.
On the rx2620 that I use, there actually is an 8TB region (though not
backed by physical memory, and 8TB really is a lot more readable than
8589934592KB.
2. pad the size field with leading spaces to further improve readability

to further improve readability.

4. Use %d instead of %u for the index field, as i is a signed int.

Compilation of 2.6.25-rc2-mm1 on ia64 generates many warnings.
IA64 support 2 ELF format (IA64 binary and IA32 binary),
thus if 2 elf related header included, cause many warning or error.
about 2 week ago, J. Bruce Fields proposed this problem fixed patch.

When !CONFIG_SMP, cpu_physical_id() is ia64_get_lid(), which is
functionally identical to
(ia64_getreg(_IA64_REG_CR_LID) >> 16) & 0xffff
so there's no need for two versions of this code.

Commit ed7b1889da256977574663689b598d88950bbd23 removed page.h from
include/asm-generic/Kbuild so that it shouldn't get exported.
However, it was redundantly listed in asm-mn10300/Kbuild and
asm-x86/Kbuild too. Remove those as well, so it really stops being
exported on those architectures. Also remove the redundant listing of
ptrace.h and termios.h from mn10300.

When using aes-xcbc-mac for authentication in IPsec,
the kernel crashes. It seems this algorithm doesn't
account for the space IPsec may make in scatterlist for authtag.
Thus when crypto_xcbc_digest_update2() gets called,
nbytes may be less than sg[i].length.
Since nbytes is an unsigned number, it wraps
at the end of the loop allowing us to go back
into loop and causing crash in memcpy.
I used update function in digest.c to model this fix.
Please let me know if it looks ok.

The XTS blockmode uses a copy of the IV which is saved on the stack
and may or may not be properly aligned. If it is not, it will break
hardware cipher like the geode or padlock.
This patch encrypts the IV in place so we don't have to worry about
alignment.
