Sure, no problem:

1. yes it can
2. the tool & library were initially created to use MSR registers. So it will work on legacy kernels as long as there is MSR kernel driver available. The downside of MSR interface is that the technologies can be managed on logical core basis only - no task or process tracking capability.
   Going forward, as these technologies get adopted into upstream kernel the tool will be extended to support kernel interfaces, too. See PID monitoring option.
3. Latest known to me status of the patchset you refer to is that it not upstream yet

Just a final note on the topic:

• mixed use of MSR and kernel interfaces to manage CAT or CMT & MBM may lead to unexpected behavior

I hope it helps.
