As I said - with the option turned on, the kernel doesn't build. If you didn't see this yourself, yet, I don't understand why you're concerned. drivers/pci/msi.c depends on the symbols set_intr_gate and interrupt, both of which aren't available in either 32- or 64-bit paravirtualized kernels. If this is functionality that can legitimately be used here, someone will first have to take the time to actually implement it; until then it should be disabled to prevent build failures (there are several other build options that I likely will submit disabling patches for, even though the functionality isn't necessarily restricted to native kernels).
