Hi,

This series advertises new instruction CPUIDs to userspace, which are
supported by Intel Diamond Rapids platform.

I've attached the spec link for each (family of) instruction in each
patch. Since the instructions included in this series don't require
additional enabling work, pass them through to guests directly.

This series is based on the master branch at the commit 23cb64fb7625
("Merge tag 'soc-fixes-6.18-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc").

Thanks for your review!

Best Regards,
Zhao

I think these can wait for the next merge window since the corresponding
QEMU code will be released around the same time as 6.20.

May I ask if this patch series can now be a candidate materials for v6.20?
