[PATCH 0/3] selftests: Remove duplicate CPUID wrappers

[Reinette Chatre <reinette.chatre@intel.com>]

A few tests that require running CPUID do so with a private
implementation of a wrapper for CPUID. This duplication of
the CPUID wrapper should be avoided but having one is also
unnecessary because of the existence of a macro that can
be used instead.

This series replaces private CPUID wrappers with calls
to the __cpuid_count() macro from cpuid.h as made available
by gcc and clang/llvm.
