[S390] IRQs too early enabled.
setup_lowcore() calls ctl_set_bit() which returns withs interrupts enabled. The setup arch code is not supposed to enable interrupts that early. Therefore use the __ctl_set_bit() variant. This fixes the not working lock dependency validator on non 64 bit systems. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
