REG_BIT() and REG_GENMASK() were intended to work with both constant expressions and otherwise, with the former having extra compile time checks for the bit ranges. Incredibly, the result of __builtin_constant_p() is not an integer constant expression when given a non-constant expression, leading to errors in BUILD_BUG_ON_ZERO(). Replace __builtin_constant_p() with the __is_constexpr() magic spell.

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.
