Definitely, we've just got a report about this, I'll have a look once I'm at the office. I'd like to check that we don't obviously break another arch by just removing percpu. If at least shuffling them around is sufficient that'd be nice. Otherwise we'll likely need a separate header (which is not a bad thing for the long term). Thanks! Willy
