This patch refactors the vfio_ap device driver to use the AP bus's ap_get_qdev() function to retrieve the vfio_ap_queue struct containing information about a queue that is bound to the vfio_ap device driver. The bus's ap_get_qdev() function retrieves the queue device from a hashtable keyed by APQN. This is much more efficient than looping over the list of devices attached to the AP bus by several orders of magnitude.

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.
