Missing set?

Looking at int-handler.S the code testing the CAUSE register($12) against
the STATUS register($13).  It only processes if both bits in the
two registers are set.  Somehow the clock is being set in the STATUS 
register and I am getting hardware interrupts - which is a good sign.

After having looked for about an hour for where the STATUS register is 
set, I seem to be unable to find where that happens.  In the case
of the dz driver, I believe that the kernel is generating interrupts, but
because the STATUS register is not set, the kernel is ignoring these

I would think the STATUS register should be set in request_irq - but
it isn't.

Where is the code that sets the STATUS bit for the clock?  and in general
for irqs?

Am I totally missing the mark here?

Given enough eyeballs all bugs seem shallow.
