Matthew Rosato 08b6e22b85 s390/pci: Mark all VFs as not implementing PCI_COMMAND_MEMORY
For s390 we can have VFs that are passed-through without the associated
PF. Firmware provides an emulation layer to allow these devices to
operate independently, but is missing emulation of the Memory Space
Enable bit.  For these as well as linked VFs, set no_command_memory
which specifies these devices do not implement PCI_COMMAND_MEMORY.

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.

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.
