[GIT PULL] arm64 fixes for -rc5

[Will Deacon]

Hi Linus,

Here is the promised second batch of arm64 fixes. The summary is in the
tag, but it's all spread around a bit. We've also had a couple more
fixes come in overnight, so I'll send you some more next week once
they've had time to sit in -next.

Cheers,

Will
