[V5 PATCH 22/26] x86: get pg_data_t's memory from other node

2012-10-29 Thread Lai Jiangshan
From: Yasuaki Ishimatsu 

If system can create movable node which all memory of the
node is allocated as ZONE_MOVABLE, setup_node_data() cannot
allocate memory for the node's pg_data_t.
So when memblock_alloc_nid() fails, setup_node_data() retries
memblock_alloc().
