This was using module_init, but the current Kconfig situation is
as follows:
In arch/x86/kernel/cpu/Makefile:
obj-$(CONFIG_CPU_SUP_INTEL) += perf_event_intel_pt.o perf_event_intel_bts.o
and in arch/x86/Kconfig.cpu:
config CPU_SUP_INTEL
default y
bool "Support Intel processors" if PROCESSOR_SELECT
So currently, the end user can not build this code into a module.
If in the future, there is desire for this to be modular, then
it can be changed to include <linux/module.h> and use module_init.
But currently, 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.
