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
