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
