Personally, I'd like to see both, but in separate files:

1. /proc/irq/current would be useful for debugging the
interrupt usage of a device and its driver.

2. /proc/irq/all would be useful for when one has an ISA
bus non-PnP card to plug into a computer and needs to
determine an IRQ it can be jumpered to.

However, this is probably unlikely to be accepted.

Best wishes from Riley.
