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
