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'."
