Merge tag 's390-6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

 - Large cleanup of the con3270/tty3270 driver. Among others this fixes:
     - Background Color Support
     - ASCII Line Character Support
     - VT100 Support
     - Geometries other than 80x24

 - Cleanup and improve cmpxchg() code. Also add cmpxchg_user_key() to
   uaccess functions, which will be used by KVM to access KVM guest
   memory with a specific storage key

 - Add support for user space events counting to CPUMF

 - Cleanup the vfio/ccw code, which also allows now to properly support
   2K Format-2 IDALs

 - Move kernel page table allocation and initialization to decompressor,
   which finally allows to enter the kernel with dynamic address
   translation enabled. This in turn allows to get rid of code with
   special handling in the kernel, which has to distinguish if DAT is on
   or off

 - Replace kretprobe with rethook

 - Various improvements to vfio/ap queue resets:
     - Use TAPQ to verify completion of a reset in progress rather than
       multiple invocations of ZAPQ.
     - Check TAPQ response codes when verifying successful completion of
       ZAPQ.
     - Fix erroneous handling of some error response codes.
     - Increase the maximum amount of time to wait for successful
       completion of ZAPQ

 - Rework system call wrappers to get rid of alias functions, which were
   only left on s390

 - Cleanup diag288_wdt watchdog driver. It has been agreed on with
   Guenter Roeck that this goes upstream via the s390 tree

 - Add missing loadparm parameter handling for list-directed ECKD
   ipl/reipl

 - Various improvements to memory detection code

 - Remove arch_cpu_idle_time() since the current implementation is
   broken, and allows user space observable accounted idle times which
   can temporarily decrease

 - Add Reset DAT-Protection support: (only) allow to change PTEs from RO
   to RW with a new RDP instruction. Unlike the currently used IPTE
   instruction, this does not necessarily guarantee that TLBs of all
   CPUs are synchronously flushed; and that remote CPUs can see spurious
   protection faults. The overall improvement for not requiring an all
   CPU synchronization, like it is required with IPTE, should be
   beneficial

 - Fix KFENCE page fault reporting

 - Smaller cleanups and improvement all over the place
