I tried to post several round of this patch set, but haven't got more time to merge it.
Steve Capper from ARM proposed both HUGEPAGE and THP in below link,
http://lists.infradead.org/pipermail/linux-arm-kernel/2013-February/148451.html

Look https://wiki.linaro.org/LEG/Engineering/Kernel/HugePages here to find what you needs.

Hi,
Apologies for the delay, I am working on rebasing HugeTLB+THP for 3.10-rc1. An
issue with PROT_NONE has arisen, and I'm currently fixing this.

Cheers,

Steve, Bill and Will

Thanks all for the response. So I understand this will get merged eventually to a future kernel version. If this is true, I would like to pull in the latest and give it a try on our Cortex A15 SMP ARM platform. We haven't upstream-ed this machine, but have plan to do so this year. I am on 3.8.4 kernel currently (due to dependency with RT Preempt patch) and will start using this patch and let you know the feedback.  BTW, do you see any issues with using this patch with RT Preempt kernel patch and also on A15 SMP kernel?

Thanks
