This small patchset refines the ambiguous naming in kvm_pmu structure
and use macros instead of magic numbers to manipulate FIXED_CTR_CTRL MSR
to increase readability.
No logic change is introduced in this patchset.

So, it looks like the 1st patch is also in the upcoming RFCv2 for
mediated passthrough vPMU. I will remove that from my list then.
Thanks. Regards

Mingwei, we'd better keep this patch in RFCv2 until the this patchset is
merged, then we don't rebase it again when this patch is merged. Thanks.

yeah. too late. I don't want to have a duplicate patch in LKML. On the
other hand, you could have waited a little bit before sending this
one. Next time, coordinate with us before sending.
Thanks.

This patch has nothing to do with the mediated vPMU patchset in theory and
can be merged earlier than the mediated vPMU patcheset which may need a
long time to review and discuss. I hope this patch can be merged ASAP and
so readers won't be mislead by the ambiguous suffix.
