Are Yes, at least for features that do not need specific new kernel support. And it looks like most (all?) of the these features will be perf only. The advantage of the scheme is that it avoids the major problems we had with updates in the past where userland and kernel had to be updated in lock-step. > the user land patches for cpu detection already in the oprofile > repository?
