Martin Schwidefsky 395e6aa1d0 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.
