By "really wanted to" -- do you mean future changes that someone might do?
Since currently, I can't see how this could be modular. We have...
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 this seems always built in to me, in the current code base.
Paul.
