Hi all,

There may be build failures in this tree due to the percpu changes in the
akpm tree.

This tree fails (more than usual) the powerpc allyesconfig build.

Changes since 20140305:

The powerpc tree still had its build failure.

The wireless-next tree still had its build failure so I reverted 2
commits and disabled a staging driver.

The gpio tree lost its build failurex.

The omap_dss2 tree lost its build failure.

The staging tree gained a conflict against the staging.current tree.

The char-misc tree still had its 2 build failures for which I reverted 2
commits.

The akpm-current tree gained a build failure for which I applied a fix
patch.

The akpm tree gained 2 build failure for which I reverted 3 commits.

Non-merge commits (relative to Linus' tree): 6117
 6735 files changed, 574777 insertions(+), 445255 deletions(-)
(the shortstat with -M -C looks like this:
 6133 files changed, 250710 insertions(+), 139830 deletions(-)
so there is a bit of movement of files going on.)

----------------------------------------------------------------------------

I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/next/ ).  If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one.  You should use "git fetch" as mentioned in the FAQ on the wiki
(see below).

You can see which trees have been included by looking in the Next/Trees
file in the source.  There are also quilt-import.log and merge.log files
in the Next directory.  Between each merge, the tree was built with
a ppc64_defconfig for powerpc and an allmodconfig for x86_64 and a
multi_v7_defconfig for arm. After the final fixups (if any), it is also
built with powerpc allnoconfig (32 and 64 bit), ppc44x_defconfig and
allyesconfig (this fails its final link) and i386, sparc, sparc64 and arm
defconfig.

Below is a summary of the state of the merge.

I am currently merging 210 trees (counting Linus' and 28 trees of patches
pending for Linus' tree).

Stats about the size of the tree over time can be seen at
http://neuling.org/linux-next-size.html .

Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next .  If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.

Thanks to Randy Dunlap for doing many randconfig builds.  And to Paul
Gortmaker for triage and bug fixes.

There is a wiki covering stuff to do with linux-next at
http://linux.f-seidel.de/linux-next/pmwiki/ .  Thanks to Frank Seidel.

FWIW, it looks like the magic combination of options are:
	- CONFIG_DEBUG_PREEMPT=y
	- CONFIG_SLUB=y
	- CONFIG_SLUB_STATS=y

Looks like the new percpu() checks are complaining about SLUB's use of
__this_cpu_inc() for maintaining it's stat counters.  The below patch
seems to fix it.

Although, I'm wondering how exact these statistics need to be.  Is
making them preemption safe even a concern?

Thanks,
  Josh

Make slub statistics maintenance preemption-safe.

Fixes the following warning when CONFIG_SLUB_STATS and
CONFIG_DEBUG_PREEMPT:

Not sure about that. You solution makes it preempt safe. If is can be
tolerated that its racy then raw_cpu_inc() could be used.

Looks like there is a similar issue in touch_softlockup_watchdog too:

Don't know if the change to this_cpu_write() is the right way here too.

Well yes lets change that to this_cpu_write(). I doubt there are
significant performance issues here.
