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.

Initial commit for merging A7000/NC with the RISCPC in order to get _one_
...
bootable GENERAL kernel for the 3 machines.
This is done by integrating the ARM7500 in a better way. In various places
the IOMD ID is checked and action is taken at runtime compared to
compiletime.
The small piece of assembler that is changed now uses the flag
`arm7500_ioc_found' that is set up by iomd.c at startup. When this chip
isnt found at startup it will skip reading the ARM7500 extended IRQ
registers and wont clear them either.
The next step will be getting the mode-definition files to the bootloader.
Currently they are compiled in.

Add a pmap_map_ptes function to map another process page table entries into the current pmap (similair to pmap_pte) but this allows multiple use of it, rather than repeated calls of pmap_pte for pte, map_ptes returns a pointer to the va where the entries were mapped so it can be reused ptes can be found by indexing into it.
...
Update some of the functions that use pmap_pte to pmap_map_ptes.
Note that there's a dummy macro for pmap_unmap_ptes, this is because at some point locking will be needed, so we need to be able to unlock them.
Performance gain seems to be minimal, however long term it should help improve things.
This is similair to the i386 pmap_map_ptes, however it's based on a version from Richard Earnshaw.
