    Merge tag 'powerpc-4.12-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
    
    Pull powerpc fixes from Michael Ellerman:
     "Mostly fairly minor, of note are:
    
       - Fix percpu allocations to be NUMA aware
    
       - Limit 4k page size config to 64TB virtual address space
    
       - Avoid needlessly restoring FP and vector registers
    
      Thanks to Aneesh Kumar K.V, Breno Leitao, Christophe Leroy, Frederic
      Barrat, Madhavan Srinivasan, Michael Bringmann, Nicholas Piggin,
      Vaibhav Jain"
