The Fine Grained Trap extension is pretty messy as it doesn't consistently use the same polarity for all trap bits. A bunch of them, added later in the life of the architecture, have a *negative* priority. So if these bits are disabled, they must be RES1 and not RES0. But that's not what the code implements, making the traps for these negative trap bits being always on instead of disabled. Fix the relevant bits, and stick a brown paper bag on my head for the rest of the day...

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 reStructuredText 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.
