Assuming that there is agreement about the perf tool ibs
implementation, could you consider to apply the (kernel) patches? Not
sure what Arnaldo's plan is for the userland. It would be great to
have both ready for 3.3.

(Even if Peter is on vacation or so, except the fix in
perf_ibs_handle_irq() the kernel patches are unchanged and Peter
already agreed to apply them.)

Thanks,

-Robert
