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
