Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull more s390 updates from Martin Schwidefsky: "Three notable larger changes next to the usual bug fixing: - update the email addresses in MAINTAINERS for the s390 folks to use the simpler linux.ibm.com domain instead of the old linux.vnet.ibm.com - an update for the zcrypt device driver that removes some old and obsolete interfaces and add support for up to 256 crypto adapters - a rework of the IPL aka boot code" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (23 commits) s390: correct nospec auto detection init order s390/zcrypt: Support up to 256 crypto adapters. s390/zcrypt: Remove deprecated zcrypt proc interface. s390/zcrypt: Remove deprecated ioctls. s390/zcrypt: Make ap init functions static. MAINTAINERS: update s390 maintainers email addresses s390/ipl: remove reipl_method and dump_method s390/ipl: correct kdump reipl block checksum calculation s390/ipl: remove non-existing functions declaration s390: assume diag308 set always works s390/ipl: avoid adding scpdata to cmdline during ftp/dvd boot s390/ipl: correct ipl parmblock valid checks s390/ipl: rely on diag308 store to get ipl info s390/ipl: move ipl_flags to ipl.c s390/ipl: get rid of ipl_ssid and ipl_devno s390/ipl: unite diag308 and scsi boot ipl blocks s390/ipl: ensure loadparm valid flag is set s390/qdio: lock device while installing IRQ handler s390/qdio: clear intparm during shutdown s390/ccwgroup: require at least one ccw device ...
