[S390] raw_local_save_flags/raw_local_irq_restore type check
Make sure that raw_local_save_flags and raw_local_irq_restore always get an unsigned long parameter. raw_irqs_disabled should call raw_local_save_flags instead of local_save_flags. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
