Merge branch 'drm-next-4.8' of git://people.freedesktop.org/~agd5f/li…

…nux into drm-next

A few more patches for 4.8.  Mostly bug fixes and some prep work
for iceland powerplay support.  I have a couple polaris patches and
Edward's misc cleanups that require a merge with Linus'.  I don't know
if you are planning a merge anytime soon.

[airlied: fixed up endian vs 32-bit change in ppatomctrl]
