[GIT PULL] arm64: fixes for -rc4

[Will Deacon <will.deacon@arm.com>]

Hi Linus,

Please pull the following arm64 fixes for 4.1. The main change is actually
a revert, after some (currently unused) branch patching code introduced
during the merge window was found to have some problems.

Cheers,

Will
