Pull percpu changes from Tejun Heo:
 "Two smallish changes for percpu.  Two patches to remove unused
  this_cpu_xor() and one to fix a bug in percpu init failure path so
  that it can reach the proper BUG() instead of oopsing earlier"

  x86: remove this_cpu_xor() implementation
  percpu: remove this_cpu_xor() implementation
