Martin Schwidefsky 50a15981a1 [S390] reference bit testing for unmapped pages ... On x86 a page without a mapper is by definition not referenced / old. The s390 architecture keeps the reference bit in the storage key and the current code will check the storage key for page without a mapper. This leads to an interesting effect: the first time an s390 system needs to write pages to swap it only finds referenced pages. This causes a lot of pages to get added and written to the swap device. To avoid this behaviour change page_referenced to query the storage key only if there is a mapper of the page. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>		2011-07-24 10:48:00 +02:00
