BTW. David: Any reason why you wouldn't let me change all occurences
of spin_{lock,unlock}_irq into the ...{save,restore} versions ?
IMO... even though you do lose a tiny bit of performance, I definitely prefer the save/restore versions.
It allows the arch a lot more flexibility, so I even have a [weak]
argument that {save,restore} variants increase portability. And it's
safer, as I like to avoid code which winds up doing (as it passes
through layers) spin_unlock_irq() followed by spin_unlock_irqrestore().Jeff
