Subject: [PATCH 0/8] mm, x86, powerpc: Consolidate pkey code

This is a rework of Ram's series, which broke the build on both arches at
various points due to the differing header dependencies.

The actual pkey changes are basically the same, this just has some rework to
get the headers cleaned up a bit beforehand.

If no one objects I'll ask Stephen to put these in a topic branch in
linux-next, and I or someone else can merge them for 4.18.

cheers
