Reading this code bordered on painful, what with all the repetition and pointless return values. More fundamentally, dribbling the hardware enables and disables in one bit at a time incurs needless system register overhead for chained events and on reset. We already use bitmask values for the KVM hooks, so consolidate all the register accesses to match, and make a reasonable saving in both source and object code.

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.
