Revert45e29d119e("x86/syscalls: Make __X32_SYSCALL_BIT be unsigned long") and add a comment to discourage someone else from making the same mistake again. It turns out that some user code fails to compile if __X32_SYSCALL_BIT is unsigned long. See, for example [1] below.

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.
