Change INT0 trigger mode from edge-sense mode to level-sense mode,
in order to fix the following timeout error:
'NETDEV WATCHDOG: eth0: transmit timed out'.
This patch is required only for the Mappi platform.

With the introduction of kernelcore=, a configurable zone is created on
request. In some cases, this value will be small enough that some nodes
contain only ZONE_MOVABLE. On some NUMA configurations when this occurs,
arch-independent zone-sizing will get the size of the memory holes within
the node incorrect. The value of present_pages goes negative and the boot
fails.
This patch fixes the bug in the calculation of the size of the hole. The
test case is to boot test a NUMA machine with a low value of kernelcore=
before and after the patch is applied. While this bug exists in early
kernel it cannot be triggered in practice.
This patch has been boot-tested on a variety machines with and without
kernelcore= set.

EDAC has a foundation to perform software memory scrubbing, but it requires a
per architecture (atomic_scrub) function for performing an atomic update
operation. Under X86, this is done with a
lock: add [addr],0
in the file asm-x86/edac.h
This patch provides the MIPS arch with that atomic function, atomic_scrub() in
asm-mips/edac.h

This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner
and the previous fixes for EDAC_MC and EDAC_DEVICE.
It removes the old (and incorrect) completion model and uses reference counts
on per instance kobjects and on the edac core module.
This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI
code was missed. In addition, this fixes a system hang after a low level
driver was unloaded. (A cleanup function was called twice, which really
screwed things up)

This fixes a deadlock that could occur on a 'setup' and 'teardown' sequence of
the workq for a edac_mc control structure instance. A similiar fix was
previously implemented for the edac_device code.
In addition, the edac_mc device code there was missing code to allow the workq
period valu to be altered via sysfs control.
This patch adds that fix on the code, and allows for the changing of the
period value as well.

Nathan Lynch <ntl@pobox.com> reported:
2.6.23-rc1 breaks the build for 64-bit powerpc for me (using
maple_defconfig):
LD vmlinux.o
powerpc64-unknown-linux-gnu-ld: dynreloc miscount for
kernel/built-in.o, section .opd
powerpc64-unknown-linux-gnu-ld: can not edit opd Bad value
make: *** [vmlinux.o] Error 1
However, I see a possibly related binutils patch:
http://article.gmane.org/gmane.comp.gnu.binutils/33650
It was tracked down to be caused by the weak prototype
declaration in mm.h:
__attribute__((weak)) const char *arch_vma_name(struct vm_area_struct *vma);
But there is no need to make the declaration weak - only the definition
needs to be marked weak. So drop the weak declaration. And in the process
drop the duplicate definition in page.h for powerpc.
Note: the arch_vma_name fix for x86_64 needs to be applied first to avoid
breaking x86_64

ext[234]_check_descriptors sanity checks block group descriptor geometry at
mount time, testing whether the block bitmap, inode bitmap, and inode table
reside wholly within the blockgroup. However, the inode table test is off
by one so that if the last block in the inode table resides on the last
block of the block group, the test incorrectly fails. This is because it
tests the last block as (start + length) rather than (start + length - 1).
This can be seen by trying to mount a filesystem made such as:
mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024
which yields:
EXT2-fs error (device loop0): ext2_check_descriptors: Inode table for group 0 not in group (block 101)!
EXT2-fs: group descriptors corrupted!
There is a similar bug in e2fsprogs, patch already sent for that.
(I wonder if inside(), outside(), and/or in_range() should someday be
used in this and other tests throughout the ext filesystems...)

In usual, migrate_pages(page,,) is called with holding mm->sem by system call.
(mm here is a mm_struct which maps the migration target page.)
This semaphore helps avoiding some race conditions.
But, if we want to migrate a page by some kernel codes, we have to avoid
some races. This patch adds check code for following race condition.
1. A page which page->mapping==NULL can be target of migration. Then, we have
to check page->mapping before calling try_to_unmap().
2. anon_vma can be freed while page is unmapped, but page->mapping remains as
it was. We drop page->mapcount to be 0. Then we cannot trust page->mapping.
So, use rcu_read_lock() to prevent anon_vma pointed by page->mapping from
being freed during migration.

Davi fixed a missing cast in the __put_user(), that was making timerfd
return a single byte instead of the full value.
Talking with Michael about the timerfd man page, we think it'd be better to
use a u64 for the returned value, to align it with the eventfd
implementation.
This is an ABI change. The timerfd code is new in 2.6.22 and if we merge this
into 2.6.23 then we should also merge it into 2.6.22.x. That will leave a few
early 2.6.22 kernels out in the wild which might misbehave when a future
timerfd-enabled glibc is run on them.
mtk says: The difference would be that read() will only return 4 bytes, while
the application will expect 8. If the application is checking the size of
returned value, as it should, then it will be able to detect the problem (it
could even be sophisticated enough to know that if this is a 4-byte return,
then it is running on an old 2.6.22 kernel). If the application is not
checking the return from read(), then its 8-byte buffer will not be filled --
the contents of the last 4 bytes will be undefined, so the u64 value as a
whole will be junk.

u32* volatile cyclone_timer means volatile auto pointer to u32,
which is clearly not what had been intended (we never even take
the address of that variable, let alone pass it to something that
could change it behind our back). u32 volatile * is what the
authors apparently wanted to say, but in reality we don't need that
qualifier there at all - it's (properly) only passed to iomem helpers
which takes care of that stuff just fine.
