Merge tag 's390-5.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull more s390 updates from Vasily Gorbik:

 - Fix physical vs virtual confusion in some basic mm macros and
   routines. Caused by __pa == __va on s390 currently.

 - Get rid of on-stack cpu masks.

 - Add support for complete CPU counter set extraction.

 - Add arch_irq_work_raise implementation.

 - virtio-ccw revision and opcode fixes.
