Subject: Uncached allocator: Handle memoryless nodes
From: Lee Schermerhorn <lee.schermerhorn@xxxxxx>
The checks for node_online in the uncached allocator are made to make sure
that memory is available on these nodes. Thus switch all the checks to use
the node_memory and for_each_memory_node functions.
