[perfmon2] multiple definition of `per_cpu__saved_global_ctrl'

Kernel 2.6.29.5, vanilla, patched from perfmon-new-base-090622. I get the following error: CC arch/x86/perfmon/perfmon_pebs_core_smpl.o CC arch/x86/perfmon/perfmon_amd64.o CC arch/x86/perfmon/perfmon_intel_atom.o CC arch/x86/perfmon/perfmon_intel_nhm.o LD arch/x8

> But it depends on what you want to do. I want to be able to build a kernel that can run pfmon on a Xeon CPU. I don't really mind exactly what version of kernel. Is there a kernel+patch combination that will work? Thanks. -
