Subject: [GIT PULL] arm64: fixes for -rc5

Hi Linus,

Here are some arm64 fixes for -rc5. The only non-trivial change (in
terms of the diffstat) is fixing our SVE ptrace API for big-endian
machines, but the majority of this is actually the addition of
much-needed comments and updates to the documentation to try to avoid
this mess biting us again in future.

There are still a couple of small things on the horizon, but nothing
major at this point.

Please pull. Thanks,

Will
