Merge tag 's390-5.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Vasily Gorbik:

 - Raise minimum supported machine generation to z10, which comes with
   various cleanups and code simplifications (usercopy/spectre
   mitigation/etc).

 - Rework extables and get rid of anonymous out-of-line fixups.

 - Page table helpers cleanup. Add set_pXd()/set_pte() helper functions.
   Covert pte_val()/pXd_val() macros to functions.

 - Optimize kretprobe handling by avoiding extra kprobe on
   __kretprobe_trampoline.

 - Add support for CEX8 crypto cards.

 - Allow to trigger AP bus rescan via writing to /sys/bus/ap/scans.

 - Add CONFIG_EXPOLINE_EXTERN option to build the kernel without COMDAT
   group sections which simplifies kpatch support.

 - Always use the packed stack layout and extend kernel unwinder tests.

 - Add sanity checks for ftrace code patching.

 - Add s390dbf debug log for the vfio_ap device driver.

 - Various virtual vs physical address confusion fixes.

 - Various small fixes and improvements all over the code.
