Merge tag 's390-5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

 - Add support for function error injection.

 - Add support for custom exception handlers, as required by
   BPF_PROBE_MEM.

 - Add support for BPF_PROBE_MEM.

 - Add trace events for idle enter / exit for the s390 specific idle
   implementation.

 - Remove unused zcore memmmap device.

 - Remove unused "raw view" from s390 debug feature.

 - AP bus + zcrypt device driver code refactoring.

 - Provide cex4 cca sysfs attributes for cex3 for zcrypt device driver.

 - Expose only minimal interface to walk physmem for mm/memblock. This
   is a common code change and it has been agreed on with Mike Rapoport
   and Andrew Morton that this can go upstream via the s390 tree.

 - Rework of the s390 vmem/vmmemap code to allow for future memory hot
   remove.

 - Get rid of FORCE_MAX_ZONEORDER to finally allow for order-10
   allocations again, instead of only order-8 allocations.

 - Various small improvements and fixes.
