Martin Schwidefsky af0ebc40a8 s390/mm,kvm: fix software dirty bits vs. kvm for old machines ... For machines without enhanced supression on protection the software dirty bit code forces the pte dirty bit and clears the page protection bit in pgste_set_pte. This is done for all pte types, the check for present ptes is missing. As a result swap ptes and other not-present ptes can get corrupted. Add a check for the _PAGE_PRESENT bit to pgste_set_pte before modifying the pte value. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>		2013-10-15 13:47:57 +02:00
