kselftest.h makes the __cpuid_count() macro available to conveniently call the CPUID instruction. Remove the local CPUID wrapper and use __cpuid_count() from kselftest.h instead. __cpuid_count() from kselftest.h is used instead of the macro provided by the compiler since gcc v4.4 (via cpuid.h) because the selftest needs to be supported with gcc v3.2, the minimal required version for stable kernels.

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.
