Correct. The fixes are beyond what we can do in .32 - and for .33 i outlined (with a patch) that we should be using not just the ftrace ring-buffer (like your patch did) but perf events to expose MCE events.
That brings MCE events to a whole new level of functionality.
Event injection support would be an interesting new addition to kernel/perf_event.c: non-MCE user-space wants to inject events as well - both to simulate rare events, and to define their own user-space events.
Is there any technical reason why we wouldnt want to take this far superior approach?
