Linus Torvalds d710d370c4 s390 updates for the 5.18 merge window

- 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.
