GIT PULL] arm64 fixes for -rc4

[Will Deacon]

Hi Linus,

Please can you pull these arm64 fixes for -rc4? It's all fairly simple
and there's a summary in the tag; Paul has reviewed the trivial RCU change.

The main issue remaining at this stage is the ongoing irqtracing problem
[1]. People are working on it, but no patches yet.

Cheers,

Will
