Michal Hocko 79b63f12ab mm, hugetlb: do not allocate non-migrateable gigantic pages from movable zones 
alloc_gigantic_page doesn't consider movability of the gigantic hugetlb
when scanning eligible ranges for the allocation.  As 1GB hugetlb pages
are not movable currently this can break the movable zone assumption
that all allocations are migrateable and as such break memory hotplug.

Reorganize the code and use the standard zonelist allocations scheme
that we use for standard hugetbl pages.  htlb_alloc_mask will ensure
that only migratable hugetlb pages will ever see a movable zone.
