    Pull powerpc updates from Michael Ellerman:
     "Notable changes:
    
       - Support for split PMD page table lock on 64-bit Book3S (Power8/9).
    
       - Add support for HAVE_RELIABLE_STACKTRACE, so we properly support
         live patching again.
    
       - Add support for patching barrier_nospec in copy_from_user() and
         syscall entry.
    
       - A couple of fixes for our data breakpoints on Book3S.
    
       - A series from Nick optimising TLB/mm handling with the Radix MMU.
    
       - Numerous small cleanups to squash sparse/gcc warnings from Mathieu
         Malaterre.
    
       - Several series optimising various parts of the 32-bit code from
         Christophe Leroy.
    
       - Removal of support for two old machines, "SBC834xE" and "C2K"
         ("GEFanuc,C2K"), which is why the diffstat has so many deletions.
    
      And many other small improvements & fixes.
    
      There's a few out-of-area changes. Some minor ftrace changes OK'ed by
      Steve, and a fix to our powernv cpuidle driver. Then there's a series
      touching mm, x86 and fs/proc/task_mmu.c, which cleans up some details
      around pkey support. It was ack'ed/reviewed by Ingo & Dave and has
      been in next for several weeks.
