[PATCH] hugepage: Make {alloc,free}_huge_page() local
Originally, mm/hugetlb.c just handled the hugepage physical allocation path
and its {alloc,free}_huge_page() functions were used from the arch specific
hugepage code. These days those functions are only used with mm/hugetlb.c
itself. Therefore, this patch makes them static and removes their
prototypes from hugetlb.h. This requires a small rearrangement of code in
mm/hugetlb.c to avoid a forward declaration.
This patch causes no regressions on the libhugetlbfs testsuite (ppc64,
POWER5).
