From: Naoya Horiguchi
Date: Tue Jun 15 2010 - 00:20:33 EST


Hi Andi-san,

Andrew and Mel gave me an improvement.
Could you put this patch on top of hwpoison branch in your tree?

Thanks,
Naoya Horiguchi

CONFIG_HUGETLBFS controls hugetlbfs interface code.
OTOH, CONFIG_HUGETLB_PAGE controls hugepage management code.
So we should use CONFIG_HUGETLB_PAGE here.
