Thomas Gleixner 1ff2fb982c x86/aperfperf: Make it correct on 32bit and UP kernels
The utilization of arch_scale_freq_tick() for CPU frequency readouts is
incomplete as it failed to move the function prototype and the define
out of the CONFIG_SMP && CONFIG_X86_64 #ifdef.

Make them unconditionally available.

Fixes: bb6e89df90 ("x86/aperfmperf: Make parts of the frequency invariance code unconditional")

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.
