Subject: Memoryless node: Allow profiling data to fall back to other nodes
From: Lee Schermerhorn <lee.schermerhorn@xxxxxx>
Processors on memoryless nodes must be able to fall back to remote nodes in
order to get a profiling buffer. This may lead to excessive NUMA traffic but
I think we should allow this rather than failing.
