Many of our enumerations follow a standard scheme where the values can be treated as signed however there are some where the value must be treated as signed and others that are simple enumerations where there is no clear ordering to the values. Provide new field types SignedEnum and UnsignedEnum which allows the signedness to be specified in the sysreg definition and emit a REG_FIELD_SIGNED define for these which is a boolean corresponding to our current FTR_UNSIGNED and FTR_SIGNED macros. Existing Enums will need to be converted, since these do not have a define generated anyone wishing to use the sign of one of these will need to explicitly annotate that field so nothing should start going wrong by default.

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.
