hugetlb: support boot allocate different sizes
Make some infrastructure changes to allow boot-time allocation of different hugepage page sizes. - move all basic hstate initialisation into hugetlb_add_hstate - create a new function hugetlb_hstate_alloc_pages() to do the actual initial page allocations. Call this function early in order to allocate giant pages from bootmem. - Check for multiple hugepages= parameters Acked-by: Adam Litke <agl@us.ibm.com> Acked-by: Nishanth Aravamudan <nacc@us.ibm.com> Acked-by: Andrew Hastings <abh@cray.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
