Yes, exactly what I was going to suggest. These are sufficiently useful
to other potential users that I think they should go in hugeutils.c from
the start. Other than that,
Current kernels have a bug in the brk() codepath. This path, unlike
the mmap() path, doesn't check if the newly allocated region
intersects a hugepage dedicated region. This means it can create a
normalpage VMA which extends into a hugepage-only address region (at
least on powerpc, which has such
