Currently some parts of the codebase will test for CONFIG_COMPAT before testing is_compat_task(). is_compat_task() is a inlined function only present on CONFIG_COMPAT. On the other hand, for !CONFIG_COMPAT, we have in linux/compat.h: #define is_compat_task() (0) Since we have this define available in every usage of is_compat_task() for !CONFIG_COMPAT, it's unnecessary to keep the ifdefs, since the compiler is smart enough to optimize-out those snippets on CONFIG_COMPAT=n This requires some regset code as well as a few other defines to be made available on !CONFIG_COMPAT, so some symbols can get resolved before getting optimized-out.

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.
