We currently don't support grouping in the emulated VGIC, which is a
known defect on KVM (not hurting any currently used guests as far as
we're aware). This is currently handled by treating all interrupts as
group 0 interrupts for an emulated GICv2 and always signaling interrupts
as group 0 to the virtual CPU interface.
However, when reading which group interrupts belongs to in the guest
from the emulated VGIC, the VGIC currently reports group 1 instead of
group 0, which is misleading. Fix this temporarily before introducing
full group support by changing the hander to _raz instead of _rao.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
