The 32-bit code is in a weird spot. Some 32-bit builds (non-PAE) do not even have NX support. Even PAE builds that support NX have to contend with things like EFI data and code mixed in the same pages where W+X is unavoidable. The folks still running X86_32=y kernels are unlikely to care much about NX. That combined with the fundamental inability fix _all_ of the W+X things means this code had little value on X86_32=y. Disable the checks.

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.
