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
