Subject: [PATCH Bug fix 0/5] Bug fix for physical memory hot-remove.

Here are some bug fix patches for physical memory hot-remove. All these
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.


Lai Jiangshan (1):
  Bug-fix: mempolicy: fix is_valid_nodemask()

Tang Chen (3):
  Bug fix: Do not split pages when freeing pagetable pages.
  Bug fix: Fix section mismatch problem of
    release_firmware_map_entry().
  Bug fix: Fix the doc format in drivers/firmware/memmap.c

Wen Congyang (1):
  Bug fix: consider compound pages when free memmap
