svm_recalc_instruction_intercepts() is always called at least once
before the vCPU is started, so the setting or clearing of the RDTSCP
intercept can be dropped from the TSC_AUX virtualization support.

What stable tree(s) are you wanting this applied to (same for the others
in this series)?  It's already in the 6.1.56 release, and the Fixes tag
is for 5.19, so I don't see where it could be missing from?

I tink it's missing in the (destined for 6.7) tree that Michael is basing this series on, so he's cherry picking it from Linus's tree.
