Subject: [GIT PULL] arm64: Fixes for -rc1

Hi Linus,

Please pull these arm64 fixes for -rc1. The big one is a fix for the VHE
enabling path during early boot, where the code enabling the MMU wasn't
necessarily in the identity map of the new page-tables, resulting in a
consistent crash with 64k pages. In fixing that, we noticed some missing
barriers too, so we added those for the sake of architectural compliance.

Other than that, just the usual merge window trickle. There'll be more
to come, too.

Cheers,

Will
