fa4e4d9668 Rework the pmap_release code to not have to walk the ptpt, it now uses a uvm_object to track the allocated vm_pages, this means it can free off the entries in the uvm_object. 
Testing shows that it's about 5% faster on the make configure step for gmake.

9f04d8d670 A couple of tidy ups to pmap: 
pmap_t -> struct pmap * in pmap.c and pmap.h
kernel_pmap -> pmap_kernel() everywhere.

64b6b76a21 You must set 'HPCFB_SWAP_*' if bytes are stored in reverse order, i.e. 
little endian like order, however, usage of 'HPCFB_SWAP_*' was widely
misunderstood because it reminded you of 'RI_BSWAP' in raster operation.
Please note that 'RI_BSWAP' indicate that frame buffer byte order is different
from natural order of system while 'HPCFB_REVORDER_*' is independent of
system byte order.

8ca7d6ec9c 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.

b86053cc53 clean up pmap_k{enter_pa,remove}(): 
a page is allowed to be mapped normally when k-mapped.

b8ceed365f Improve the vac_me_harder function, it is now slightly faster, however pmap_enter_pv is also now slightly slower, so they appear to balance out. 
Note that I've some ideas in the works on how to improve the pv handling, so the slow down is short term only.

Also added non-advertising licence and copyright to myself and richard.

407440a6b3 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.
