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.

The pfn_array_alloc_pin routine is doing too much. Today, it does the alloc of the pfn_array struct and its member arrays, builds the iova address lists out of a contiguous piece of guest memory, and asks vfio to pin the resulting pages. Let's effectively revert a significant portion of commit 5c1cfb1c ("vfio: ccw: refactor and improve pfn_array_alloc_pin()") such that we break pfn_array_alloc_pin() into its component pieces, and have one routine that allocates/populates the pfn_array structs, and another that actually pins the memory. In the future, we will be able to handle scenarios where pinning memory isn't actually appropriate.
