Pull s390 updates from Martin Schwidefsky:
- Add two missing kfree calls on error paths in the vfio-ccw code
- Make sure that all data structures of a mediated vfio-ccw device are
initialized before registering it
- Fix a sparse warning in vfio-ccw
- A followup patch for the pgtable_bytes accounting, the page table
downgrade for compat processes missed a mm_dec_nr_pmds()
- Reject sampling requests in the PMU init function of the CPU
measurement counter facility
- With the vfio AP driver an AP queue needs to be reset on every device
probe as the alternative driver could have modified the device state
