* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:
[IA64] use generic compat_old_sys_readdir
[IA64] pci_acpi_scan_root cleanup
[IA64] Shrink shadow_flush_counts to a short array to save 8k of per_cpu area.
[IA64] Remove sn2_defconfig.
Switch ia64 to the generic compat_sys_old_readdir which is identical
except for slightly better error handling. Also remove sys32_getdents
which already isn't wired up to the syscall table anymore in favour of
compat_sys_getdents.

The code walks all the acpi _CRS methods to see how many windows
to allocate. It then scans them all again to insert_resource()
for each *even if the first scan found that there were none*.
Move the second scan inside the "if (windows)" clause.

Making allmodconfig will break the current build. This patch shrinks
the per_cpu__shadow_flush_counts from 16k to 8k which frees enough space
to allow allmodconfig to successfully complete.

This patch should fix TOC handling for cdroms that can not play audio. It
extends commit af744e3294 ("cdrom: don't
check CDC_PLAY_AUDIO in cdrom_count_tracks()") with a safety check and
non-audio ioctls support.
Since CDC_PLAY_AUDIO flag was used not only to check ability to play audio
but also to ensure that audio_ioctl was not NULL, all TOC-related
operations had to use it.
As far as I understand, now audio_ioctl is never NULL, so a sanity check
during device registration should be sufficient.
It was tested on Optiarc AD7203A device, that has no ability to play
audio.

x86 boot: proper use of ARRAY_SIZE instead of repeated E820MAX constant
caused these new warnings during a normal build:

define an own ARRAY_SIZE macro in boot.h, similar to the other private

Quoting Mike Travis in "x86: cleanup early per cpu variables/accesses v4"
(23ca4bba3e):
The DEFINE macro defines the per_cpu variable as well as the early
map and pointer. It also initializes the per_cpu variable and map
elements to "_initvalue". The early_* macros provide access to
the initial map (usually setup during system init) and the early
pointer. This pointer is initialized to point to the early map
but is then NULL'ed when the actual per_cpu areas are setup. After
that the per_cpu variable is the correct access to the variable.
As these variables are NULL'ed before __init sections are dropped
(in setup_per_cpu_maps), they can be safely annotated as __ref.
This change silences following section mismatch warnings:

x86_64 add/sub atomic ops does not seems to accept integer values bigger
than 32 bits as immediates. Intel's add/sub documentation specifies they
have to be passed as registers.
The only operations in the x86-64 architecture which accept arbitrary
64-bit immediates is "movq" to any register; similarly, the only
operation which accept arbitrary 64-bit displacement is "movabs" to or
from al/ax/eax/rax.
http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Machine-Constraints.html
states :
e
32-bit signed integer constant, or a symbolic reference known to fit
that range (for immediate operands in sign-extending x86-64
instructions).
Z
32-bit unsigned integer constant, or a symbolic reference known to
fit that range (for immediate operands in zero-extending x86-64
instructions).
Since add/sub does sign extension, using the "e" constraint seems appropriate.
It applies to 2.6.27-rc, 2.6.26, 2.6.25...

The intent of "flush_tlbs" is to invalidate all TLB entries by doing a
TLB invalidate instruction for all pages in the address range 0 to
0x00400000. A loop counter is set up at the high value and
decremented by page size. However, the loop is only done once as the
sense of the conditional branch at the loop end does not match the
setup/decrement. This fixes it to do the whole range by correcting
the branch condition.
