Raw event is an important part of Perf-events. It helps the user collect
performance data for events that are not listed as the generic hardware
events and cache events but ARE supported by the CPU's PMU.
This patch adds this feature for mipsxx 24K/34K/74K/1004K. For how to use
it, please refer to processor core software user's manual and the
comments for mipsxx_pmu_map_raw_event() for more details.
Please note that this is a "precise" implementation, which means the
kernel will check whether the requested raw events are supported by this
CPU and which hardware counters can be assigned for them.

Should this just be folded into the other patches?
I would also reiterate that perhaps the generic support functions be
separated from the processor specific event definitions.
