[PATCH 1/3] mm, sparse: allocate bootmem without panicing in sparse_mem_maps_populate_node

From: Sasha Levin
Date: Sun Dec 23 2012 - 15:16:27 EST


__alloc_bootmem_node_high() would panic if it failed allocating, so the fallback
would never get reached. Switch to using __alloc_bootmem_node_high_nopanic().
