From: Jiang Liu <jiang.liu@xxxxxxxxxxxxxxx>
Subject: sgi-xp: replace cpu_to_node() with cpu_to_mem() to support memoryless node
xpc_create_gru_mq_uv() allocates memory with __GFP_THISNODE flag set,
which may cause permanent memory allocation failure on memoryless node.
So replace cpu_to_node() with cpu_to_mem() to better support memoryless
node. For node with memory, cpu_to_mem() is the same as cpu_to_node().
