[GIT PULL] arm64 fixes for -rc4

[Will Deacon]

Hi Linus,

Please pull these arm64 fixes for -rc4.

It's a lot smaller than last week, with the star of the show being a
couple of fixes to head.S addressing a boot regression introduced by the
recent overhaul of that code in non-default configurations (i.e. KASLR
disabled). The first of those two resolves the issue reported (and
bisected) by Mikulus in the wait_on_bit() thread.

Cheers,

Will
