Subject: swsusp: fix memory shrinker
From: Rafael J. Wysocki <rjw@xxxxxxx>
Fix a bug in the swsusp's memory shrinker that causes some systems using
highmem to refuse to suspend to disk if image_size is set above 1/2 of
available RAM.
Special thanks to Jiri Slaby for reporting the problem and assistance in
debugging it.
