Merge tag 's390-6.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Vasily Gorbik:

 - Get rid of private VM_FAULT flags

 - Add word-at-a-time implementation

 - Add DCACHE_WORD_ACCESS support

 - Cleanup control register handling

 - Disallow CPU hotplug of CPU 0 to simplify its handling complexity,
   following a similar restriction in x86

 - Optimize pai crypto map allocation

 - Update the list of crypto express EP11 coprocessor operation modes

 - Fixes and improvements for secure guests AP pass-through

 - Several fixes to address incorrect page marking for address
   translation with the "cmma no-dat" feature, preventing potential
   incorrect guest TLB flushes

 - Fix early IPI handling

 - Several virtual vs physical address confusion fixes

 - Various small fixes and improvements all over the code
