Merge tag 's390-5.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 bug fixes from Martin Schwidefsky: - Fix overwrite of the initial ramdisk due to misuse of IS_ENABLED - Fix integer overflow in the dasd driver resulting in incorrect number of blocks for large devices - Fix a lockdep false positive in the 3270 driver - Fix a deadlock in the zcrypt driver - Fix incorrect debug feature entries in the pkey api - Fix inline assembly constraints fallout with CONFIG_KASAN=y * tag 's390-5.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: correct some inline assembly constraints s390/pkey: add one more argument space for debug feature entry s390/zcrypt: fix possible deadlock situation on ap queue remove s390/3270: fix lockdep false positive on view->lock s390/dasd: Fix capacity calculation for large volumes s390/mem_detect: Use IS_ENABLED(CONFIG_BLK_DEV_INITRD)
