Martin Schwidefsky 09b538833b [S390] fix pgste update logic ... The pgste_update_all / pgste_update_young and pgste_set_pte need to check if the pte entry contains a valid page address before the storage key can be accessed. In addition pgste_set_pte needs to set the access key and fetch protection bit of the new pte entry, not the old entry.
