Subject: [PATCH 1/3] mm, sparse: allocate bootmem without panicing in sparse_mem_maps_populate_node
Date: Sun, 23 Dec 2012 15:15:06 -0500 [thread overview]
Message-ID: <1356293711-23864-1-git-send-email-sasha.levin@oracle.com> (raw)
__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().
