        This comes with a test module which verifies all the various corner

      Merge tag 's390-5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux · 1758fedd
      Linus Torvalds authored
      Pull s390 updates from Vasily Gorbik:
      
       - 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.

       - arm64 support for syscall emulation via PTRACE_SYSEMU{,_SINGLESTEP}
      
       - Wire up VM_FLUSH_RESET_PERMS for arm64, allowing the core code to

       - Slight performance improvement by keeping softirqs enabled while
         touching the FPSIMD/SVE state (kernel_neon_begin/end)

       - Re-instate ARM64_PSEUDO_NMI support which was previously marked as
         BROKEN due to some bugs (now fixed)

         panic_smp_self_stop() to avoid warning on not being able to stop

         ARCH_DMA_MINALIGN if the system is fully coherent

       - Allow the selection of ARM64_MODULE_PLTS, currently only done via
         RANDOMIZE_BASE (and an erratum workaround), allowing modules to spill
         over into the vmalloc area

      blk-mq: fix up placement of debugfs directory of queue files · 7e41c3c9
      Greg Kroah-Hartman authored
      When the blk-mq debugfs file creation logic was "cleaned up" it was
      cleaned up too much, causing the queue file to not be created in the
      correct location.  Turns out the check for the directory being present
      is needed as if that has not happened yet, the files should not be
      created, and the function will be called later on in the initialization
      code so that the files can be created in the correct location.
      
      Fixes: 6cfc0081 ("blk-mq: no need to check return value of debugfs_create functions")
