5592ad3fbb Ignore interrupts if the device isn't open. This prevents stray interrupts 
from hosing the works.  What a stupid architecture.

2. "press any key to reboot" reads the key from the console.

4c40e74463 1. id_irq is a u_short 
2. "irq ?" sets it to (u_short)-1
3. "irq #" sets it to (1<<#)
4. not specifying an interrupt sets it to 0.

Until someone else comes up with a better scheme, that's the way it is.
If you have a driver that turns the interrupt off, set it to ZERO.

If, after calling XXprobe(), id_irq is still (u_short)-1, that is the same
as if  probe() failed.

545cc18754 This patch allows the wd device driver to tell how big the disks are on 
WD1007-derived controllers. In this example, wdc0 is a WD1007-clone,
and wdc1 is a WD1003-clone. WD1007 controllers are generally ESDI
and IDE controllers.
wdc0 at 0x1f0-0x1f7 irq 14 on isa
wd0 at wdc0 targ 0: 322MB 1224 cyl, 15 head, 36 sec <disktype>
wdc1 at 0x170-0x17f irq 7 on isa
wd2 at wdc1 targ 0: (unknown size) <disktype>

fbecd3e987 Once more: some changes to the ioconf.c structure. It will now handle 
devices hanging off controllers, any kind of controller.
A device on isa0 is called at probe(self), then attach(self)
A controller on isa0 is called at probe(self), then all it's children with
    defined unit numbers are initialized by calling attach(subdev); next all
    subdevices with unit ? are initialized by calling attach(sundev).
Almost all device entry points is now like the vax/sun model (intr being
the weird one)

cf15785585 from Rodney W. Grimes (rgrimes@agora.rain.com) (patchkit patch 117): 
This patch adds the symbol names to icu.s that vmstat expects
the interrupt counters to be called.  It also adds code to config
so that the names of the interrupts are written at the end of vectors.s
so vmstat can report real device names.  It also cleans up and enables
the logging of stray interrupts.  The counters for false interrupts
are added but the fix for them is not (the fix I have is not done
very good.) A false interrupt is when a device asserts it's interrupt
signal, then removes it before the 8259 can latch it.  This is the number
one cause of stray IRQ7's and IRQ15's.

        Additional device probe information is now printed.  This includes
ending I/O address (many drivers do not return the correct value from a
probe this still needs to be fixed), memory address and size, driver
flags passed in by config.
