Hi all,

This is version two of the patches I previously posted here:

http://lkml.kernel.org/r/1536747974-25875-1-git-send-email-will.deacon@xxxxxxx

Changes since v1 include:

* Fixed increment of the physical address around the mapping loops
* Added Reviewed-by tags from Toshi

All feedback welcome,

Will
