So now it becomes rather inconsistent:

  - PCI_DEVICE_ID_INTEL_HSW_IMC is defined in include/linux/pci_ids.h
  - PCI_DEVICE_ID_INTEL_HSW_U_IMC is defined in 
arch/x86/kernel/cpu/perf_event_intel_uncore_snb.c

Could you please also send a patch on top of this one that moves the 
other, related PCI IDs as well?

Thanks,
