The first patch should be straightforward. The second should be too, but it relates to a problem with the p6 PMU that I brought up in a separate thread. The third patch copies code over from the perf_event_intel.c interrupt handler. Unfortunately KNC and x86 architectural perfmon use different MSR numbers. The proper fix might be to make this generic and have function vectors for the status/ack functions, but since they are inline and probably performance critical I took the easy way out and just duplicated the code.
