Well, not doung anything should be ok because the *uncore* things would
go to the <vendor>/ subdir:

I.e.,

arch/x86/kernel/cpu/perf_event_amd_uncore.c
arch/x86/kernel/cpu/perf_event_intel_uncore.c
arch/x86/kernel/cpu/perf_event_intel_uncore.h
arch/x86/kernel/cpu/perf_event_intel_uncore_nhmex.c
arch/x86/kernel/cpu/perf_event_intel_uncore_snb.c
arch/x86/kernel/cpu/perf_event_intel_uncore_snbep.c

will become

arch/x86/events/amd/uncore.c
arch/x86/events/intel/uncore.c
arch/x86/events/intel/uncore.h
arch/x86/events/intel/uncore_nhmex.c
arch/x86/events/intel/uncore_snb.c
arch/x86/events/intel/uncore_snbep.c

and core.c will be in the upper dir arch/x86/events/
