Sheer suckyness on my part.. we needed a 'quick' fix to make these
CPU_SUP_* things build at all and never got around to cleaning it up
afterwards.

creation of a arch/x86/kernel/cpu/perf_event.h and enough code massage
to make all these .c files compile independently would be appreciated,
not sure that'll immediately solve your issue though.

You could slip something like it into the 'cleanup' if nothing else
presents itself :-)
