patches are based on the latest -mm tree.
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git akpm

And patch1 and patch3 are very important.
patch1: free compound pages when freeing memmap, otherwise the kernel
will panic the next time memory is hot-added.
patch3: the old way of freeing pagetable pages was wrong. We should never
split larger pages into small ones.
