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"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
