Merge tag 'powerpc-4.12-8' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:
 "Hopefully the last two powerpc fixes for 4.12.

  The CXL one is larger than I'd usually send at rc7, but it fixes new
  code this cycle, so better to have it working for the release. It was
  actually sent a few weeks back but got blocked in testing behind
  another fix that was causing issues.

  We are still tracking one crash in v4.12-rc7, but only one person has
  reproduced it and the commit identified by bisect doesn't touch any of
  the relevant code, so I think it's 50/50 whether that commit is
  actually the problem or it's some code layout / toolchain issue.

  Two fixes for code we merged this cycle:

   - cxl: Fixes for Coherent Accelerator Interface Architecture 2.0

   - Avoid miscompilation w/GCC 4.6.3 on 32-bit - don't inline
     copy_to/from_user()

  Thanks to Al Viro, Larry Finger, Christophe Lombard"
