[patch 08/10] Uncached allocator: Handle memoryless nodes

[clameter@sgi.com]

[-- Type: text/plain, Size: 1792 bytes --]

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.
