David Rientjes cbf978bfb1 oom: suppress nodes that are not allowed from meminfo on page alloc failure 
Displaying extremely verbose meminfo for all nodes on the system is
overkill for page allocation failures when the context restricts that
allocation to only a subset of nodes.  We don't particularly care about
the state of all nodes when some are not allowed in the current context,
they can have an abundance of memory but we can't allocate from that part
of memory.

This patch suppresses disallowed nodes from the meminfo dump on a page
allocation failure if the context requires it.
