[PATCH V2 0/5] Huge pages for short descriptors on ARM

Hello,
This series brings HugeTLB pages and Transparent Huge Pages (THP) to
ARM on short descriptors.

Russell, Andrew,
I would like to get this in next (and hopefully 3.16 if no problems
arise) if that sounds reasonable?

There's one patch at the beginning of the series for mm:
mm: hugetlb: Introduce huge_pte_{page,present,young}
This has been tested on ARM and s390 and should compile out for other
architectures.

The rest of the series targets arch/arm.

I've bumped the series to V2 as it was rebased (and tested against)
v3.15-rc1. On ARM the libhugetlbfs test suite, some THP PROT_NONE
tests and the recursive execve test all passed successfully.

Thanks,
