[PATCH 3/8] hugetlb: rename hugepage allocation functions
From: Naoya Horiguchi
Date: Tue Aug 24 2010 - 20:00:44 EST
The function name alloc_huge_page_no_vma_node() has verbose suffix "_no_vma".
This patch makes existing alloc_huge_page() and it's family have "_vma" instead,
which makes it easier to read.
