TSC is used to check the whether the TSC of processors are

The only thing that needs to be corrected here is that this test needs

it upstream soon!
I agree, and maybe we'd better also use smp > 1 in the test of
monotonic_time ?
Monotonic time has not this restriction, as far as I know... Unless I
am very mistaken
Yes, it does not have such restriction, but I think it would be more
reasonable
to do the test in smp > 2 especially for kvmclock as it depends on
per-vcpu data
structure and guest tsc which may have more problems during the vcpu
migration
between physical processors.
