Subject[PATCH 10/11] x86: perf_event_intel_bts.c: use arch_initcall to hook in enabling
This was using module_init, but there is no way this code can
be modular. In the non-modular case, a module_init becomes a
device_initcall, but this really isn't a device. So we should
choose a more appropriate initcall bucket to put it in.

The obvious choice here seems to be arch_initcall, but that does
make it earlier than it was currently through device_initcall.
As long as perf_pmu_register() is functional, we should be OK.
