[GIT PULL] arm64 fixes for -rc5

[Will Deacon]

Hi Linus,

Please pull this unfortunately large collection of arm64 fixes for -rc5.
Some of this is absolutely trivial, but the alternatives, vDSO and CPU
errata workaround fixes are significant. At least people are finding and
fixing these things, I suppose.

Summary in the tag.

Cheers,

Will
