The current TO_NATIVE() has some limitations: 1) You cannot cast the argument. 2) You cannot pass a variable marked as 'const'. 3) Passing an array is a bug, but it is not detected. Impelement TO_NATIVE() using bswap_*() functions. These are GNU extensions. If we face portability issues, we can port the code from include/uapi/linux/swab.h. With this change, get_rel_type_and_sym() can be simplified by casting the arguments directly.

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.
