[PATCH v2 1/5] x86: get pg_data_t's memory from other node

2012-11-23 Thread Tang Chen
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(). Signed-off-by: Yasuaki Ishimatsu
