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
