Subject: [GIT PULL] Please pull powerpc/linux.git powerpc-4.15-2 tag

Hi Linus,

Please pull some powerpc fixes for 4.15.

These would be nice to have in rc1, but none of them are actually that
crucial. So they can wait until Monday if you're busy eating pumpkin


The following changes since commit 3ffa9d9e2a7c10127d8cbf91ea2be15390b450ed:

  powerpc/64s: Fix Power9 DD2.0 workarounds by adding DD2.1 feature (2017-11-15 14:25:42 +1100)

are available in the Git repository at: powerpc-4.15-2

  powerpc/64s: Fix Power9 DD2.1 logic in DT CPU features (2017-11-22 23:17:01 +1100)

powerpc fixes for 4.15 #2

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

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.
