Merge branch 'for-rmk/hugepages' of git://git.linaro.org/people/stevecapper/linux into devel-stable
These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM. Only long descriptors (LPAE) are supported
in this series.
The code has been tested on an Arndale board (Exynos 5250).
