Subject: [GIT PULL] s390 patches for the 5.18 merge window

Hello Linus,

please pull s390 changes for 5.18. There is a merge conflict with kvm
tree you've pulled already. A change had to be included in both trees
as prerequisite for other changes. Your tree:

1a82f6ab2365 ("s390/uaccess: Add copy_from/to_user_key functions")

will get conflicts in arch/s390/lib/uaccess.c with the changes from
s390 tree:

432b1cc78e98 ("s390/uaccess: Add copy_from/to_user_key functions")
4efd417f298b ("s390: raise minimum supported machine generation to z10")
731efc9613ee ("s390: convert ".insn" encoding to instruction names")

please simply take the version from s390 tree (removing bunch of code from
arch/s390/lib/uaccess.c file).

I also had to pull our fixes in, to resolve dependencies and avoid merge
conflict, hence there are couple of s390 MAINTAINERS changes in the log,
you've already pulled with our fixes for 5.17-rc4.

Thank you,
Vasily

  s390/test_unwind: add kretprobe tests (2022-03-10 15:58:17 +0100)

----------------------------------------------------------------
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.
