xen_tsc_khz() doesn't use CPUID but really *should*.

Care to pull in
https://lore.kernel.org/all/20260509224824.3264567-31-dwmw2@xxxxxxxxxxxxx/
to your next round please?

(Without the misplaced changes in kvm/x86.c that should have been in
two different prior commits, and are now folded into those correctly in
my kvmclock5 branch ready for the next posting of that).

I'll drop that patch, and the similar x86/kvm one which you *have*
already taken in this series, from my next posting.

Thanks.
