The patch titled
swsusp: take lowmem reserves into account
has been added to the -mm tree. Its filename is
swsusp-take-lowmem-reserves-into-account.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: "Rafael J. Wysocki" <rjw@xxxxxxx>
swsusp allocates memory from the normal zone, so it cannot use lowmem
reserve pages from the lower zones. Therefore it should not count these
pages as available to it.
