I wish it was so, but we do need to override the native routines that
manipulate the hw interrupt state when the I-pipe is enabled, and using
the irqflags framework will still require the implementation to provide
the raw_local_irq* helpers linux/irqflags.h requires, in some arch-dep
companion file for the Blackfin. This is the one we want to patch for
the I-pipe, to get them virtualized.
