Mel Gorman 76ab0f530e mm: compaction: add /proc trigger for memory compaction ...

Add a proc file /proc/sys/vm/compact_memory.  When an arbitrary value is
written to the file, all zones are compacted.  The expected user of such a
trigger is a job scheduler that prepares the system before the target
application runs.
