Subject: [PATCH 0/5] Add movablecore_map boot option.

This patchset provide a boot option for user to specify ZONE_MOVABLE memory
map for each node in the system.

movablecore_map=nn[KMG]@ss[KMG]

This option make sure memory range from ss to ss+nn is movable memory.
1) If the range is involved in a single node, then from ss to the end of
   the node will be ZONE_MOVABLE.
2) If the range covers two or more nodes, then from ss to the end of
   the node will be ZONE_MOVABLE, and all the other nodes will only
   have ZONE_MOVABLE.
3) If no range is in the node, then the node will have no ZONE_MOVABLE
   unless kernelcore or movablecore is specified.
4) This option could be specified at most MAX_NUMNODES times.
5) If kernelcore or movablecore is also specified, movablecore_map will have
   higher priority to be satisfied.
6) This option has no conflict with memmap option.

Tang Chen (4):
  page_alloc: add movable_memmap kernel parameter
  page_alloc: Sanitize movablecore_map.
  page_alloc: Limit movable zone areas with movablecore_map parameter
  page_alloc: Bootmem limit with movablecore_map

Yasuaki Ishimatsu (1):
  x86: get pg_data_t's memory from other node
