Merge branch 'for-3.3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull per-cpu patches from Tejun Heo:
"This pull request contains four patches. One replaces manual clearing
with bitmap_clear(), two fix generic definition of __this_cpu ops so
that they don't choose unnecessarily strict arch version. One makes
_this_cpu definition use raw_local_irq_*() so that it doesn't end up
wrecking irq on/off state tracking when used from inside lockdep.
Of the four patches, the raw_local_irq_*() update is the most
important, so please feel free to cherry pick only that one patch and
ignore the rest if you want to - commit e920d5971d 'percpu: use
raw_local_irq_* in _this_cpu op'."
* 'for-3.3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
percpu: fix __this_cpu_{sub,inc,dec}_return() definition
percpu: use raw_local_irq_* in _this_cpu op
percpu: fix generic definition of __this_cpu_add_and_return()
percpu: use bitmap_clear
