Hi Linus,
please pull more s390 updates for 5.19 merge window.
Just a couple of small improvements, bug fixes and cleanups.
Thanks,
Heiko

s390/stack: add union to reflect kvm stack slot usages (2022-06-01 12:03:17 +0200)
----------------------------------------------------------------
more s390 updates for 5.19 merge window
- Add Eric Farman as maintainer for s390 virtio drivers.
- Improve machine check handling, and avoid incorrectly injecting a machine
check into a kvm guest.
- Add cond_resched() call to gmap page table walker in order to avoid
possible huge latencies. Also use non-quiesing sske instruction to speed
up storage key handling.
- Add __GFP_NORETRY to KEXEC_CONTROL_MEMORY_GFP so s390 behaves similar like
common code.
- Get sie control block address from correct stack slot in perf event
code. This fixes potential random memory accesses.
- Change uaccess code so that the exception handler sets the result of
get_user() and __get_kernel_nofault() to zero in case of a fault. Until
now this was done via input parameters for inline assemblies. Doing it
via fault handling is what most or even all other architectures are
doing.
- Couple of other small cleanups and fixes.
