Pull s390 updates from Martin Schwidefsky:

 - A larger update for the zcrypt / AP bus code:
    + Update two inline assemblies in the zcrypt driver to make gcc happy
    + Add a missing reply code for invalid special commands for zcrypt
    + Allow AP device reset to be triggered from user space
    + Split the AP scan function into smaller, more readable functions

 - Updates for vfio-ccw and vfio-ap
    + Add maintainers and reviewer for vfio-ccw
    + Include facility.h in vfio_ap_drv.c to avoid fragile include chain
    + Simplicy vfio-ccw state machine

 - Use the common code version of bust_spinlocks

 - Make use of the DEFINE_SHOW_ATTRIBUTE

 - Fix three incorrect file permissions in the DASD driver

 - Remove bit spin-lock from the PCI interrupt handler

 - Fix GFP_ATOMIC vs GFP_KERNEL in the PCI code
