Raw Blame History

We keep with the idea behind this patch but adjust all of the changes
to match the existing impelementations in RHEL 7.3.
commit 0b5395f052ee09cd7e3d219af4e805c38058afb5
Author: H.J. Lu <hjl.tools@gmail.com>

Update x86_64 multiarch functions for <cpu-features.h>
This patch updates x86_64 multiarch functions to use the newly defined
HAS_CPU_FEATURE, HAS_ARCH_FEATURE and LOAD_RTLD_GLOBAL_RO_RDX from
<cpu-features.h>.
