Migrate on Fault stats:

pgs loc checked -- pages found in swap/migration cache by do_swap_page()
	with zero page_mapcount() and otherwise "stable".

pages misplacd -- of the "loc checked" pages, the number that were found
	to be misplaced relative to the mempolicy in effect--vma, task
	or system default.

pages migrated -- All pages migrated:  migrate-on-fault, mbind(), ...
	Exceeds the misplaced pages in the stats above because the
	test load included programs that migrated memory regions about
	using mbind() with the MPOL_MF_MOVE flag.

Auto-migration Stats:

tasks migrated - number of internode task migrations.  Each of these
	migrations resulted in the task walking its address space
	looking for anon pages in vmas with local allocation policy.
	Includes kicks via /proc/<pid>/migrate.

pages scanned -- total number of pages examined as candidates for
	auto-migration in mm/mempolicy.c:check_range() as a result
	of internode task migration or /proc/<pid>/migrate scans.

pages selected -- Anon pages selected for auto-migration.
	If lazy auto-migration is enabled [default], these pages
	will be unmapped to allow migrate-on-fault to migrate
	them if and when a task faults the page.  If lazy auto-
	migration is disabled, these pages will be directly
	migrated [pulled] to the destination node.

pages failed -- the number of the selected pages that the
	kernel failed to unmap for lazy migration or failed
	to direct migrate.

Migration Cache Statistics:

pgs added -- the number of pages added to the migration cache.
	This occurs when pages are unmapped for lazy migration.

pgs removd -- the number of pages removed from the migration
	cache.  This occurs when the last pte referencing the
	cache entry is replaced with a present page pte.
	The nummber of pages added less the number removed
	is the number of pages still in the cache.

duplicates -- count of migration_duplicate() calls, usually
	via swap_duplicate(), to add a reference to a migration
	cache entry.  This occurs when a page in the migration
	cache is unmapped in try_to_unmap_one() and when a task
	with anon pages in the migration cache forks and all of
	its anon pages become COW shared with the child in
	copy_one_pte().

refs freed -- count of migration cache entry reference freed,
	usually via one of the swap cache free functions.
	When the reference count on a migration cache entry
	goes zero, the entry is removed from the cache.  Thus,
	the number of pages added plus the number of duplicates
	should equal the number of refs freed plus the number
	of pages still in the cache [adds - removes].
