oops, attached patch should fix that, but I needed to change
following patches:

  perf c2c report: Add cacheline hists processing
  perf c2c report: Decode c2c_stats for hist entries

I updated perf/c2c_v4 branch with the fix and rebased
to your current perf/core.. let me know if I need to
repost

thanks,
