s390/mm: try to avoid storage key operation in ptep_set_access_flags The call to pgste_set_key in ptep_set_access_flags can be avoided if the old pte is found to be valid at the time the new access rights are set. The function that created the old, valid pte already completed the required storage key operation. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
