Merge tag 's390-6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:
- Add vfio-ap support to pass-through crypto devices to secure
execution guests
- Add API ordinal 6 support to zcrypt_ep11misc device drive, which is
required to handle key generate and key derive (e.g. secure key to
protected key) correctly
- Add missing secure/has_secure sysfs files for the case where it is
not possible to figure where a system has been booted from. Existing
user space relies on that these files are always present
- Fix DCSS block device driver list corruption, caused by incorrect
error handling
- Convert virt_to_pfn() and pfn_to_virt() from defines to static inline
functions to enforce type checking
- Cleanups, improvements, and minor fixes to the kernel mapping setup
- Fix various virtual vs physical address confusions
- Move pfault code to separate file, since it has nothing to do with
regular fault handling
- Move s390 documentation to Documentation/arch/ like it has been done
for other architectures already
- Add HAVE_FUNCTION_GRAPH_RETVAL support
- Factor out the s390_hypfs filesystem and add a new config option for
it. The filesystem is deprecated and as soon as all users are gone it
can be removed some time in the not so near future
- Remove support for old CEX2 and CEX3 crypto cards from zcrypt device
driver
- Add support for user-defined certificates: receive user-defined
certificates with a diagnose call and provide them via 'cert_store'
keyring to user space
- Couple of other small fixes and improvements all over the place
