Merge branch 'fixes' into next
Merge our fixes branch from the 4.16 cycle.
There were a number of important fixes merged, in particular some Power9
workarounds that we want in next for testing purposes. There's also been
some conflicting changes in the CPU features code which are best merged
and tested before going upstream.
