Pull s390 updates from Martin Schwidefsky:
 "common I/O layer
   - Fix bit-fields crossing storage-unit boundaries in css_general_char

  dasd driver
   - Avoid a sparse warning in regard to the queue lock
   - Allocate the struct dasd_ccw_req as per request data. Only for
     internal I/O is the structure allocated separately
   - Remove the unused function dasd_kmalloc_set_cda
   - Save a few bytes in struct dasd_ccw_req by reordering fields
   - Convert remaining users of dasd_kmalloc_request to
     dasd_smalloc_request and remove the now unused function

  vfio/ccw
   - Refactor and improve pfn_array_alloc_pin/pfn_array_pin
   - Add a new tracepoint for failed vfio/ccw requests
   - Add a CCW translation improvement to accept more requests as valid
   - Bug fixes"
