Merge tag 's390-6.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull more s390 updates from Heiko Carstens:

 - Various virtual vs physical address usage fixes

 - Add new bitwise types and helper functions and use them in s390
   specific drivers and code to make it easier to find virtual vs
   physical address usage bugs.

   Right now virtual and physical addresses are identical for s390,
   except for module, vmalloc, and similar areas. This will be changed,
   hopefully with the next merge window, so that e.g. the kernel image
   and modules will be located close to each other, allowing for direct
   branches and also for some other simplifications.

   As a prerequisite this requires to fix all misuses of virtual and
   physical addresses. As it turned out people are so used to the
   concept that virtual and physical addresses are the same, that new
   bugs got added to code which was already fixed. In order to avoid
   that even more code gets merged which adds such bugs add and use new
   bitwise types, so that sparse can be used to find such usage bugs.

   Most likely the new types can go away again after some time

 - Provide a simple ARCH_HAS_DEBUG_VIRTUAL implementation

 - Fix kprobe branch handling: if an out-of-line single stepped relative
   branch instruction has a target address within a certain address area
   in the entry code, the program check handler may incorrectly execute
   cleanup code as if KVM code was executed, leading to crashes

 - Fix reference counting of zcrypt card objects

 - Various other small fixes and cleanups
