[ upstream commit 1da5c9bc119d3a749b519596b93f9b2667e93c4a ] IA32 support on 64bit kernels depends on whether CONFIG_IA32_EMULATION is selected or not. As it is a compile time option it doesn't provide the flexibility to have distributions set their own policy for IA32 support and give the user the flexibility to override it. As a first step introduce ia32_enabled() which abstracts whether IA32 compat is turned on or off. Upcoming patches will implement the ability to set IA32 compat state at boot time.

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.
