Hi Linus,

please pull s390 fixes and features for 4.20

The following changes since commit 55a5542a546238354d1f209f794414168cf8c71d:

s390/hibernate: fix error handling when suspend cpu != resume cpu (2018-09-20 13:20:23 +0200)

are available in the git repository at:

s390/pkey: move pckmo subfunction available checks away from module init (2018-10-22 08:37:46 +0200)

----------------------------------------------------------------
s390 updates for the 4.20 merge window

- 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
