Linus Torvalds 75013c6c52 - Make sure PMU internal buffers are flushed for per-CPU events too and 
properly handle PID/TID for large PEBS.
 
 - Handle the case properly when there's no PMU and therefore return an
   empty list of perf MSRs for VMX to switch instead of reading random
   garbage from the stack.
