Oh, right. We have to let them go in together.

Hi Peter,

I have verified that the V8 kernel part patch is compatible with both latest
tip and latest perf/core. We don't need to rebase.
The user perf tool for tip is not updated yet. We need to merge latest
perf/core to tip before applying user part patch.

Do you have more comments for the code?

The latest kernel and user part codes are here.
