Fine Grained Traps are fun. Not. Implement the fine grained trap forwarding, reusing the Coarse Grained Traps infrastructure previously implemented. Each sysreg/instruction inserted in the xarray gets a FGT group (vaguely equivalent to a register number), a bit number in that register, and a polarity. It is then pretty easy to check the FGT state at handling time, just like we do for the coarse version (it is just faster).

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.
