Subject: [GIT PULL] arm64 fixes for -rc1

Hi Linus,

Please pull these arm64 fixes for -rc1. The usual summary is in the tag,
but the main fix is for the fast GUP lockless page-table walk when we
have a combination of compile-time and run-time folding of the p4d and
the pud respectively.

Cheers,

Will
