Linus Torvalds 1758feddb0 s390 updates for the 5.3 merge window
- Improve stop_machine wait logic: replace cpu_relax_yield call in generic
    stop_machine function with a weak stop_machine_yield function. This is
    overridden on s390, which yields the current cpu to the neighbouring cpu
    after a couple of retries, instead of blindly giving up the cpu to the
    hipervisor. This significantly improves stop_machine performance on s390 in
    overcommitted scenarios.
    This includes common code changes which have been Acked by Peter Zijlstra
    and Thomas Gleixner.
 
  - Improve jump label transformation speed: transform jump labels without
    using stop_machine.
 
  - Refactoring of the vfio-ccw cp handling, simplifying the code and
    avoiding unneeded allocating/copying.
 
  - Various vfio-ccw fixes (ccw translation, state machine).
 
  - Add support for vfio-ap queue interrupt control in the guest.
    This includes s390 kvm changes which have been Acked by Christian
    Borntraeger.
 
  - Add protected virtualization support for virtio-ccw.
 
  - Enforce both CONFIG_SMP and CONFIG_HOTPLUG_CPU, which allows to remove some
    code which most likely isn't working at all, besides that s390 didn't even
    compile for !CONFIG_SMP.
 
  - Support for special flagged EP11 CPRBs for zcrypt.
 
  - Handle PCI devices with no support for new MIO instructions.
 
  - Avoid KASAN false positives in reworked stack unwinder.
 
  - Couple of fixes for the QDIO layer.
 
  - Convert s390 specific documentation to ReST format.
 
  - Let s390 crypto modules return -ENODEV instead of -EOPNOTSUPP if hardware is
    missing. This way our modules behave like most other modules and which is
    also what systemd's systemd-modules-load.service expects.
 
  - Replace defconfig with performance_defconfig, so there is one config file
    less to maintain.
 
  - Remove the SCLP call home device driver, which was never useful.
 
  - Cleanups all over the place.
