[GIT PULL] more s390 updates for 5.19 merge window

[Heiko Carstens]

Hi Linus,

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

Thanks,
Heiko

The following changes since commit 94d3477897481b92874654455e263e0b1728acb5:

  s390/head: get rid of 31 bit leftovers (2022-05-18 13:31:07 +0200)

are available in the Git repository at:

  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.
