Pull up revision 1.9 (requested by thorpej in ticket #568):
  Change the way DMA map syncs are done.  Instead of remembering
  the virtual address for each DMA segment, just cache a
  pointer to the original buffer/buftype used to load the
  DMA map, and use that.  Shrinks bus_dma_segment_t from 12
  to 8 bytes, and the cache flushing is also more efficient.

Use separate function pointers for dmamap_sync pre- vs post- operations.
Change the bus_dmamap_sync() macro to test the ops argument against pre-
and post- constants.  The compiler will optimize out dead code because
of the constants.  Since post- operations are not needed on ARM (except
for ISA bounce buffers), this eliminate a large number of function calls
which are noops, each of which cost at least 6 cycles just in the call
and return overhead (not to mention whatever other useless work the
compiler decides to do in the callee).

Overhaul how DMA ranges work in the ARM bus_dma implementation.

A new "arm32_dma_range" structure now describes a DMA window, with
a system address base, bus address base, and length.  In addition to
providing info about which memory regions are legal for DMA, the new
structure provides address translation support, as well.

As before, if a tag does not list any ranges, then all addresses are
considered valid, and no DMA address translation is performed.

This allows us to remove a large chunk of code which was duplicated and
tweaked slightly (to do the address translation) from the stock ARM
bus_dma in the XScale IOP and ARM Integrator ports.

Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.

Change the way that DMA map syncs are done.  Instead of remembering
the virtual address for each DMA segment, just cache a pointer to the
original buffer/buftype used to load the DMA map, and use that.  This
lets us shrink the bus_dma_segment_t down from 12 bytes to 8, and the
cache flushing is also more efficient.

Tested on an i80321 -- changes to others are mechanical.

  Significant cleanup, here, including better PTE bit names.
* Add XScale PTE extensions (ECC enable, write-allocate cache mode).
* Mechanical changes everywhere else to update for new pte.h.  While
  doing this, two bugs (as a result of typos) were fixed in

	arm/arm32/bus_dma.c
	evbarm/integrator/int_bus_dma.c

Overhaul bus_dmamap_sync for the ARM:
* Track which process (XXX really, vmspace) owns the mapping.  When
  we sync the map, if the mapping doesn't belong to the kernel or to
  the current process (XXX really, vmspace), then no cache fobbing
  is necessary, since the cache is Wb-Inv'd on context switch (XXX need
  to revisit this when we support FCSE).
* Be smarter about which cache operation we do when sync'ing the map:
  - PREREAD -- Invalidate D$ (XXX right now, we actually do Wb-Inv)
  - PREWRITE -- Write-back D$ (note, we do NOT invalidate here)
  - PREREAD|PREWRITE -- Wb-Inv D$

More work is needed here.  In particular, a version for CPUs
with write-through caches should be provided, to eliminate
the write-back steps (which are noops on such CPUs, but skipping
two branches would be nice).

Overhaul of the ARM cache code.  This is mostly a simplification
pass.  Rather than providing a whole slew of cache operations that
aren't ever used, distill them down to some useful primitives:

	icache_sync_all         Synchronize I-cache
	icache_sync_range       Synchronize I-cache range

	dcache_wbinv_all        Write-back and Invalidate D-cache
	dcache_wbinv_range      Write-back and Invalidate D-cache range
	dcache_inv_range        Invalidate D-cache range
	dcache_wb_range         Write-back D-cache range

	idcache_wbinv_all       Write-back and Invalidate D-cache,
				Invalidate I-cache
	idcache_wbinv_range     Write-back and Invalidate D-cache,
				Invalidate I-cache range

Note: This does not yet include an overhaul of the actual asm files
that implement the primitives.  Instead, we've provided a safe default
for each CPU type, and the individual CPU types can now be optimized
one at a time.
