base/SOURCES/glibc-rh1292018-2.patch

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>.
