Christian Borntraeger cb1863a461 [S390] add types.h include to s390_ext.h
The header file for external interrupts uses the _u16 type. Make sure
that _u16 is defined by including linux/types.h. This prevents compile
failures, if asm/s390_ext.h is the first include file.

Heiko Carstens 8da1aecde0 [S390] Improve __smp_call_function_map.
There is no need to disable bottom halves when holding call_lock. Also
this could imply that it is legal to call smp_call_function* from
bh context, which it is not.
Also test if func will be executed locally before disabling
and aterwards enabling interrupts again. It's not necessary to disable
and enable interrupts each time __smp_call_function_map gets called.

Linus Torvalds 602033ed59 Revert most of "x86: Fix alternatives and kprobes to remap write-protected kernel text"
This reverts most of commit 19d36ccdc3.

The way to DEBUG_RODATA interactions with KPROBES and CPU hotplug is to
just not mark the text as being write-protected in the first place.
Both of those facilities depend on rewriting instructions.

Having "helpful" debug facilities that just cause more problem is not
being helpful.  It just adds complexity and bugs. Not worth it.

Mel Gorman b5445f956e Allow nodes to exist that only contain ZONE_MOVABLE
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.

Doug Thompson 39c29657fc include/asm-:mips add missing edac h file
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

Doug Thompson d4c1465b7d drivers/edac: fix edac_pci sysfs
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

In addition, the edac_mc device code there was missing code to allow the workq

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:

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

Eric Sandeen 780dcdb211 fix inode_table test in ext234_check_descriptors
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...)

KAMEZAWA Hiroyuki dc386d4d1e memory unplug: migration by kernel
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.

Davide Libenzi 098284020c make timerfd return a u64 and fix the __put_user
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.

Ryusuke Konishi 70f38db60c PM: fix compiler error of PPC dart_iommu
A dummy inline function of register_nosave_region_late was accidentally
removed by the recent PM patch that introduced suspend notifiers.
This elimination causes the following compiler error on PPC machines.
