Pull s390 updates from Martin Schwidefsky:

 - A copy of Arnds compat wrapper generation series

 - Pass information about the KVM guest to the host in form the control
   program code and the control program version code

 - Map IOV resources to support PCI physical functions on s390

 - Add vector load and store alignment hints to improve performance

 - Use the "jdd" constraint with gcc 9 to make jump labels working again

 - Remove amode workaround for old z/VM releases from the DCSS code

 - Add support for in-kernel performance measurements using the CPU
   measurement counter facility

 - Introduce a new PMU device cpum_cf_diag to capture counters and store
   thenn as event raw data.

 - Bug fixes and cleanups
