The architecture has added more information about faults to ISS2 within ESR. Add decode of this to our data abort fault decode to aid diagnostics. Features that are not currently enabled are included here for completeness. Since the architecture specifies the values of bits within ISS2 in terms of ISS2 rather than in terms of the register as a whole we do so for our definitions as well, this makes it easier to review bitfield definitions.

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.
