Merge tag 's390-6.10-8' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Heiko Carstens:

 - Fix and add physical to virtual address translations in dasd and
   virtio_ccw drivers. For virtio_ccw this is just a minimal fix.
   More code cleanup will follow.

 - Small defconfig updates
