I'm not ELRepo but I don't think they can do that until/unless RH
fix the compilers in the distro to be retpoline aware. If they do.<br class="">
<br class="">
And, in any case, Intel have pretty much said "don't use the new
microcode" so there is no working microcode available that the
kernel can use anyway. All the vendors have pulled their BIOS
updates and backed out e.g. the microcode_ctl updates.<br class="">

We provide these kernels for hardware testing in
an effort to identify<br class="">
new/updated drivers which can then be targeted
for backporting as kmod<br class="">
packages. Meanwhile, these kernels may provide
interim relief to<br class="">
people with non-functional hardware. We stress
that we consider such<br class="">
kernels as a last resort for those who are
unable to get their<br class="">
hardware working using the RHEL-7 kernel with
supplementary kmod<br class="">
packages.<br class="">
<br class="">
These packages are provided "As-Is" with no
implied warranty or<br class="">
support. Using the kernel-ml may expose your
system to security,<br class="">
performance and/or data corruption issues. Since
timely updates may<br class="">
not be available from the ELRepo Project, the
end user has the<br class="">
ultimate responsibility for deciding whether to
continue using the<br class="">
kernel-ml packages in regular service.<br class="">
<br class="">
The packages are intentionally named kernel-ml
so as not to conflict<br class="">
with the RHEL-7 kernels and, as such, they may
be installed and<br class="">
updated alongside the regular kernel. The kernel
configuration is<br class="">
based upon a default RHEL-7 configuration with
added functionality<br class="">
enabled as appropriate.<br class="">
<br class="">
If a bug is found when using these kernels, the
end user is encouraged<br class="">
to report it upstream to the Linux Kernel Bug
Tracker [1] and, for our<br class="">
reference, to the ELRepo bug tracker [2]. By
taking such action, the<br class="">
reporter will be assisting the kernel
developers, Red Hat and the Open<br class="">
Source Community as a whole.<br class="">
<br class="">
Thank you,<br class="">
<br class="">
