Since 2.6.32 the kernel has supported pseudo-anonymous mmaps for
huge pages without having hugetlbfs mounted. This patch adds a
check for that kernel feature.

hugetlbfs_prefault relies on having a file descriptor associated with
the huge page backed region to prefault the huge pages. This patch
gives an alternative for prefaulting which will be used when the
kernel supports MAP_HUGETLB.

Now that we have the ability to map huge pages without having
an active hugetlfs mount point with MAP_HUGETLB it no longer
makes sense to detect valid page sizes based on active mount
points. This patch separates out the detection of valid page
sizes from the detection of active mount points.

As of 2.6.32 mmap supports the MAP_HUGETLB flag that will, when there are
available huge pages, return an anonymous region backed by huge pages.
This allows us to use default sized huge pages for morecore and
get_huge_pages without forcing the admin to mount hugetlbfs.
This is probably the last RF
If get_huge_pages uses MAP_HUGETLB to create a new huge page region, the
old test_addr_huge function will claim the mapping is not on a huge page.
This patch changes the test to use the new get_mapping_page_size method.

When MAP_HUGETLB is used, the standard test for a maaping being backed by huge

When the kernel supports MAP_HUGETLB use it for requesting
a huge page backed area instead of creating a file descriptor.
