Change Details

The concept of the IRQ isn't needed at this layer. The IRQ is something which belongs to the particular hardware, not the innermost layer of the kernel. Put another way intr_event is the device/interrupt source side of the interrupt, "IRQs" are an interrupt controller concept. This largely reverts commit 9b33b154b53. Many places originally modified no longer exist and a number of new locations have been added. This is still reverting a large portion of that commit. Squash review: switching `intr_{get|set}affinity()` to using proposed standard interface removing "irq" from kernel event interface switching `intr_{get|set}affinity()` to using `intr_event *`

Partially reverting 9b33b154b53. D39178 now has a proposed common interface for "irq" to interrupt structure resolution, Remaining portion is to switch `intr_{get|set}affinity()` and `_intr_drain()` to the interface. There is a question of whether the numeric value to `struct intr_event *` should be internal, versus external. Receiving a `struct intr_event *` seems more consistent with the rest of `kern_intr.c`, though all present users have the number handy. Squash review: (the original has been broken into pieces) switch `intr_{get|set}affinity()` to internally use `intr2event()`/`intrtab_lookup()` switch `intr_{get|set}affinity()` to expect `intr_event *` as argument remove "irq" argument from `intr_event_create()` remove `->ie_irq` from `struct intr_event`
