Merge tag 'powerpc-4.15-4' of git://git./linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:

 "One notable fix for kexec on Power9, where we were not clearing MMU
  PID properly which sometimes leads to hangs. Finally debugged to a
  root cause by Nick.

  A revert of a patch which tried to rework our panic handling to get
  more output on the console, but inadvertently broke reporting the
  panic to the hypervisor, which apparently people care about.

  Then a fix for an oops in the PMU code, and finally some s/%p/%px/ in
  xmon.

  Thanks to: David Gibson, Nicholas Piggin, Ravi Bangoria"
