[GIT PULL] arm64: Second round of fixes for -rc2

[Will Deacon]

Hi Linus,

As promised, here's the second round of arm64 fixes for -rc2, based on
-rc1. Details in the tag. The ACPI/IORT build fix is pretty big in the
diffstat, but it's really just the result of code movement to ensure
that the functions are guarded correctly when !CONFIG_IOMMU_SUPPORT.

Please pull.

Cheers,

Will
