Merge tag 's390-7.0-5' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Vasily Gorbik:
- Revert IRQ entry/exit path optimization that incorrectly cleared
some PSW bits before irqentry_exit(), causing boot failures with
linux-next and HRTIMER_REARM_DEFERRED (which only uncovered the
problem)
- Fix zcrypt code to show CCA card serial numbers even when the
default crypto domain is offline by selecting any domain available,
preventing empty sysfs entries
* tag 's390-7.0-5' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/zcrypt: Enable AUTOSEL_DOM for CCA serialnr sysfs attribute
s390: Revert "s390/irq/idle: Remove psw bits early"
