Merge tag 's390-4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
- Improved access control for the zcrypt driver, multiple device nodes
can now be created with different access control lists
- Extend the pkey API to provide random protected keys, this is useful
for encrypted swap device with ephemeral protected keys
- Add support for virtually mapped kernel stacks
- Rework the early boot code, this moves the memory detection into the
boot code that runs prior to decompression.
- Add KASAN support
- Bug fixes and cleanups
