[GIT PULL] arm64: post merge-window fixes for 4.1

[Will Deacon]

Hi Linus,

Please pull the following arm64 fixes for 4.1. Not too much here, but
we've addressed a couple of nasty issues in the dma-mapping code as well
as adding the halfword and byte variants of load_acquire/store_release
following on from the CSD locking bug that you fixed in the core.

Thanks,

Will
