...
(SCB_VECTOIDX(vec) - SCB_IOVECBASE] -> SCB_VECTOIDX(vec - SCB_IOVECBASE))
Sigh. This is all very good work- this new interrupt stuff. Yet like the
last time my good friend Jason 'simplified' things, we lost information.
It used to be you could tell which specific slot an interrupt was frame
based upon the vector. Now you can't because they're allocated dynamically.
Oh well- it's not all that important.

Checking a whole host of pmap changes:
...
Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.
Also implemented a page zeroing function when the processor is idling. Note that hpcarm may wish to disable this.
I believe this code to be stable, if anyone has any problems please shout up.

in pmap_remove_pv(), don't flush the MIPS1 cache when removing the last mapping.
this was added in rev 1.97, to avoid stale data being left in the cache
when the page is zeroed bypassing the cache in pmap_zero_page_uncached().
we've since found that bypassing the cache for idle-loop page zeroing
doesn't work very well anyway, so we don't do that anymore.
so now we can remove the extra cache-flush.
remove pmap_zero_page_uncached() while I'm thinking of it.
