Hi all,

Here's a first attempt at writing a perf tool that gives per cpu
information. Please let me know if there's any general interest. Make
sure to cc me. 

Attaching unofficial patch and screenshot. One good thing is it creates
an infrastructure to add more perf tools easily (just add to union).

cpu usg intrps pflts hypercls evntc  hyp Guests ------------------>
  0  93    199   330    32698   492    2   1:000:19   1:001:46   2:001:4   

Says that : cpu 0 was 93% utilized. There were 199 interrupts on this
cpu, 330 page faults, 32698 hcalls, 492 event channels. The hyp used 2%
of the cpu. Guest domid 1 had vcpu 0 use 19% of cpu, and vcpu 1 use
46%. Domid 2 had vcpu 1 use 4% and vcpu 2 use 22%

Hope you guys like it.
