Merge tag 'powerpc-4.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:
 "A small batch of fixes, about 50% tagged for stable and the rest for
  recently merged code.

  There's one more fix for the >128T handling on hash. Once a process
  had requested a single mmap above 128T we would then always search
  above 128T. The correct behaviour is to consider the hint address in
  isolation for each mmap request.

  Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in
  VAS, a fix for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly
  identify P9 DD2.1 but in code that is currently not used by default.

  Thanks to: Aneesh Kumar K.V, Christophe Leroy, Madhavan Srinivasan,
  Sukadev Bhattiprolu"
