Neither FIELD_PREP() nor *_encode_bits() can be used in constant contexts (such as initializers), but we don't want to define shift constants for all masks just for use in initializers, and having checks that the values fit is also useful. Therefore, add FIELD_PREP_CONST() which is a smaller version of FIELD_PREP() that can only take constant arguments and has less friendly (but not less strict) error checks, and expands to a constant value.

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.
