Well, that sucks. We should be removing magic global numberspaces, not adding them. > Why does this mess with all of ther GPIO controllers?

And if they don't generate interrupts, and they decide they can also just park themselves at MAX_IRQ? -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
