Subject: [GIT PULL] s390 patches for 4.18-rc2

Hi Linus,

please pull from the 'for-linus' branch of

	git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus

to receive the following updates:

  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

Shortlog:

Dong Jia Shi (4):
      vfio: ccw: fix error return in vfio_ccw_sch_event
      vfio: ccw: shorten kernel doc description for pfn_array_pin()
      vfio: ccw: refactor and improve pfn_array_alloc_pin()
      vfio: ccw: set ccw->cda to NULL defensively

Halil Pasic (2):
      vfio: ccw: push down unsupported IDA check
      vfio: ccw: add tracepoints for interesting error paths

Sebastian Ott (6):
      s390/cio: sanitize css_general_characteristics definition
      s390/dasd: simplify locking in process_final_queue
      s390/dasd: move dasd_ccw_req to per request data
      s390/dasd: remove dasd_kmalloc_set_cda
      s390/dasd: reshuffle struct dasd_ccw_req
      s390/dasd: only use preallocated requests
