A few things that sneaked in are:
The pmap change was just a tidy up of some old dead macros.

The footbridge_clock was to make the loop counter bigger, so it's a bit
more sane in terms of real timing when the hardware counter isn't
avilable due to interrupts being off.

The footbridge_irqhandler is to make the irq exit saner, rather than
reenabling hardware interrupts and taking a new interrupt, check on exit
of the irqhandler for irq's that happened while handling the higher
priority irqs.
