Borislav Petkov 2e7614c073 x86/uaccess: Remove unused __addr_ok() macro
This was caught while staring at the whole {set,get}_fs() machinery.

It's last user, the 32-bit version of strnlen_user() went away with

  5723aa993d ("x86: use the new generic strnlen_user() function")

so drop it.

No functional changes.

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.
