Merge branch 'for-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
* 'for-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: Remove irqsafe_cpu_xxx variants Fix up conflict in arch/x86/include/asm/percpu.h due to clash with cebef5beed3d ("x86: Fix and improve percpu_cmpxchg{8,16}b_double()") which edited the (now removed) irqsafe_cpu_cmpxchg*_double code.
