Subject: [perf] exporting perf_pmu_register?

Hello

I'm attempting to write a perf pmu driver as a kernel module, but
am finding this difficult to do it properly because
   perf_pmu_register
is not exported.

Would a patch similar to
  https://lkml.org/lkml/2010/8/18/64
be accepted that exported this?

I'm trying to write a RAPL/energy pmu module on a Sandybridge-EP machine
but the sysadmin won't install a custom kernel so I'm stuck trying to do 
it entirely via loadable module, and it turns out this doesn't seem to be 
possible at all :(
