Merge branch 'for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu

Pull percpu updates from Tejun Heo:
 "Contains Alex Shi's three patches to remove percpu_xxx() which overlap
  with this_cpu_xxx().  There shouldn't be any functional change."

* 'for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
  percpu: remove percpu_xxx() functions
  x86: replace percpu_xxx funcs with this_cpu_xxx
  net: replace percpu_xxx funcs with this_cpu_xxx or __this_cpu_xxx
