Merge tag 's390-4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: - A larger update for the zcrypt / AP bus code: + Update two inline assemblies in the zcrypt driver to make gcc happy + Add a missing reply code for invalid special commands for zcrypt + Allow AP device reset to be triggered from user space + Split the AP scan function into smaller, more readable functions - Updates for vfio-ccw and vfio-ap + Add maintainers and reviewer for vfio-ccw + Include facility.h in vfio_ap_drv.c to avoid fragile include chain + Simplicy vfio-ccw state machine - Use the common code version of bust_spinlocks - Make use of the DEFINE_SHOW_ATTRIBUTE - Fix three incorrect file permissions in the DASD driver - Remove bit spin-lock from the PCI interrupt handler - Fix GFP_ATOMIC vs GFP_KERNEL in the PCI code * tag 's390-4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/zcrypt: rework ap scan bus code s390/zcrypt: make sysfs reset attribute trigger queue reset s390/pci: fix sleeping in atomic during hotplug s390/pci: remove bit_lock usage in interrupt handler s390/drivers: fix proc/debugfs file permissions s390: convert to DEFINE_SHOW_ATTRIBUTE MAINTAINERS/vfio-ccw: add Farhan and Eric, make Halil Reviewer vfio: ccw: Merge BUSY and BOXED states s390: use common bust_spinlocks() s390/zcrypt: improve special ap message cmd handling s390/ap: rework assembler functions to use unions for in/out register variables s390: vfio-ap: include <asm/facility> for test_facility()
