7dd7f8baa2 Handle 64bit DMA addresses on PCI for platforms that can (currently only 
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

d88cf589cb A few ISA sound drivers like to share dma channels, and hence deferred 
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.

To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.

All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.

0b956d0b8b Implement pmc(9) -- An interface to hardware performance monitoring 
counters.  These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface.  Initially, the Intel XScale
counters are the only ones supported.

bc0d30a90c introduce "struct platform", and remove "cputype" variable. 
this change also includes a patch to obtain secondary cache size
from ARC firmware by Bob Meader, which was posted on port-arc on 18 Aug 2000.
this should make NEC Express RISCserver work.

this change obtains ID of display controller from ARC firmware, too.
