[CRIU] [PATCH 2/2] mem: Use pagemap cache

[Cyrill Gorcunov]

To test pagemap cache I run a small program which creates 1024 close
laying VMAs. Results are:

before
------

dump: {
	freezing_time: 274
	frozen_time: 41629
	memdump_time: 4659
	memwrite_time: 394
	pages_scanned: 13487
	pages_skipped_parent: 0
	pages_written: 63
	irmap_resolve: 0
}

after
-----

dump: {
	freezing_time: 202
	frozen_time: 32847
	memdump_time: 1366
	memwrite_time: 386
	pages_scanned: 13487
	pages_skipped_parent: 0
	pages_written: 63
	irmap_resolve: 0
}
