* keep track of PCI buses that aren't known by firmware, but are found
...
by NetBSD
* use this info in in intr_find_mpmapping
* get rid of the last argument to intr_find_mpmapping, it was redundant

Add hooks and structures to allow the MP table intr mapping code a
...
better shot at finding a mapping. For PCI interrupts, if a bus
has no mappings, try its parent, with the swizzled pin, and the
bridge's device number.

Move the bulk of pci_intr_string into a seperate intr_string function. Use
...
that new function to print the pciide compat interrupt in pciide_machdep.c.
Share pciide_machdep.c between amd64 and i386.

If possible, put the device name of the APIC used into the interrupt string,
...
not "apic N". This makes it easier to match vmstat output with dmesg output.

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.

Add the options MPBIOS_SCANPCI and MPACPI_SCANPCI to configure PCI roots
...
with the MPBIOS/ACPI bus information, by walking through the buses, and
descending down every bus that hasn't been marked configured yet.

Generalize bounce buffers, and use them for 32 bit PCI if needed.
...
Make ALLOCNOW the default iff bouncing might be needed (this has
no effect on i386 because ISA DMA devices already had to use
ALLOCNOW, and PCI isn't bounced (yet), since we don't do > 4G
at this point for i386.
