As we blindly reset some HFGxTR_EL2 bits to 0, we also randomly trap unsuspecting sysregs that have their trap bits with a negative polarity. ACCDATA_EL1 is one such register that can be accessed by the guest, causing a splat on the host as we don't have a proper handler for it. Adding such handler addresses the issue, though there are a number of other registers missing as the current architecture documentation doesn't describe them yet.

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.
