[PATCH] swsusp: use __GFP_WAIT
swsusp uses GFP_ATOMIC, but it can afford to use __GFP_WAIT, which will permit it to reclaim clean pagecache instead of emitting scary page-allocation-failure messages. Cc: Pavel Machek <pavel@ucw.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
