[PATCH v2 00/11] x86: xen cpuid() cleanup
Reduce special casing of xen_cpuid() by using cpu capabilities instead
of faked cpuid nodes.
This cleanup enables us remove the hypervisor specific set_cpu_features
callback as the same effect can be reached via
setup_[clear|force]_cpu_cap().
Removing the rest faked nodes from xen_cpuid() requires some more work
as the remaining cases (mwait leafs and extended topology info) have
to be handled

[PATCH v2 10/11] vmware: set cpu capabilities during platform initialization
...* kernel may miss a wrap of the counter if the vcpu is descheduled for a
- * long time. To skip these checks at runtime we set these capability bits,
- * so that the kernel could just trust the hypervisor with providing a
- * reliable virtual TSC that is suitable for timekeeping.
