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.

   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
