[PATCH 0/8] ARM/arm64 Barrier cleanups and fixes for 3.16

[Will Deacon]

Hello,

Here is the current set of barrier cleanups and fixes I plan to queue
for merging in 3.16. Most of the arm64 patches have been posted before,
but there are also a few additions that I wrote recently.

All feedback welcome,

Will
