Merge tag 's390-5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:
 "Besides all the small improvements and cleanups the most notable part
  is the fast vector/SIMD implementation of the ChaCha20 stream cipher,
  which is an adaptation of Andy Polyakov's code for the kernel.

  Summary:

   - add fast vector/SIMD implementation of the ChaCha20 stream cipher,
     which mainly adapts Andy Polyakov's code for the kernel

   - add status attribute to AP queue device so users can easily figure
     out its status

   - fix race in page table release code, and and lots of documentation

   - remove uevent suppress from cio device driver, since it turned out
     that it generated more problems than it solved problems

   - quite a lot of virtual vs physical address confusion fixes

   - various other small improvements and cleanups all over the place"
