Now that GICv2 has a proper userspace accessor for the pending state, switch GICv3 over to it, dropping the local version, moving over the specific behaviours that CGIv3 requires (such as the distinction between pending latch and line level which were never enforced with GICv2). We also gain extra locking that isn't really necessary for userspace, but that's a small price to pay for getting rid of superfluous 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.
