1722770f13 x86-boot: don't request VBE2 information
The new x86 setup code (4fd06960f1) 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).

E.G.:

get_vbe_controller_info:

(The full BIOS can be found at http://peter.korsgaard.com/vgabios.bin
if interested).

The old setup code didn't ask for VBE2 info, and the new code doesn't
actually do anything with the extra information, so the fix is to simply
not request it. Other BIOS'es might have the same problem.

609b5297bc x86: fix merge mistake in i387.c
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.

e40cd10ccf x86: clear DF before calling signal handler
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.

6d2144d355 slab: NUMA slab allocator migration bugfix
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
	cache_alloc_refill+0xe6
	kmem_cache_alloc+0xd0
	...

b621038678 slub: Do not cross cacheline boundaries for very small objects
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).

818c7e866f [IA64] update efi region debugging to use MB, GB and TB as well as KB
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

   ...
   ... (   8MB)
   ... ( 928MB)
   ... (   3MB)
   ...

   vs

   ...
   ... (8MB)
   ... (928MB)
   ... (3MB)
   ...

3. Pad the attr field out to 64bits using leading zeros,
   to further improve readability.

   ...
   mem05: type= 2, attr=0x0000000000000008, range=[0x0000000004000000-0x000000000481f000) (   8MB)
   mem06: type= 7, attr=0x0000000000000008, range=[0x000000000481f000-0x000000003e876000) ( 928MB)
   mem07: type= 5, attr=0x8000000000000008, range=[0x000000003e876000-0x000000003eb8e000) (   3MB)
   mem08: type= 4, attr=0x0000000000000008, range=[0x000000003eb8e000-0x000000003ee7a000) (   2MB)
   ...

   ...
   mem05: type= 2, attr=0x8, range=[0x0000000004000000-0x000000000481f000) (   8MB)
   mem06: type= 7, attr=0x8, range=[0x000000000481f000-0x000000003e876000) ( 928MB)
   mem07: type= 5, attr=0x8000000000000008, range=[0x000000003e876000-0x000000003eb8e000) (   3MB)
   mem08: type= 4, attr=0x8, range=[0x000000003eb8e000-0x000000003ee7a000) (   2MB)
   ...

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

N.B: This code is not compiled unless EFI_DEBUG is non 0.

2ab42e24d6 Really unexport asm/page.h
Commit ed7b1889da 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.

2f40a178e7 [CRYPTO] xcbc: Fix crash with IPsec
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.

103018aca2 [WATCHDOG] Fix declaration of struct smbios_entry_point in hpwdt
On my HP DL380 G5 system running a 64-bit kernel, loading the hpwdt
driver causes a crash because the driver attempts to ioremap an
invalid physical address.  This is because the driver has an incorrect
definition of the SMBIOS table entry point structure: the table
address is only a 32-bit quantity, and making it a u64 means that the
high-order 32 bits end up containing garbage.

Correcting the structure definition fixes the driver so that it loads
without any problems on my system.
