[PATCH] refactor macros

[Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>]

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.
