Please either use the 0x0a04 constant directly in
perf_event_intel_uncore_snb.c, or explain why the #define should be
here, e.g., maybe it will be used in multiple places. See the comment
at the top of pci_ids.h.

I'm not pushing for that, since they're already there and we haven't
tried to apply that policy retroactively.

Yes. But if we made a mistake in the past, that doesn't mean we

at the top of pci_ids.h.
But then, the same reasoning would apply to the other 3 IMC defines,
wouldn't it?
Yes. But if we made a mistake in the past, that doesn't mean we
should repeat it today.
Shall I post a patch moving the others as well?
I'm not pushing for that, since they're already there and we haven't
tried to apply that policy retroactively.
