[GIT PULL] arm64: Fixes for -rc3

[Will Deacon]

Hi Linus,

Please pull these arm64 fixes for -rc3. Summary in the tag, but we've
got a smattering of changes all over the place which we've acrued since
-rc1. To my knowledge, there aren't any pending issues at the moment,
but there's still plenty of time for something else to crop up...

Cheers,

Will
