Subject: [PATCH 0/3] selftests: Remove duplicate CPUID wrappers
Date:   Fri,  4 Feb 2022 11:17:08 -0800
Message-Id: <cover.1644000145.git.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.
