3ce3540177 Don't start the process of scanning CPUs and I/O APICs (with interrupt 
routing to follow later) if the ACPI implementation is marked as
having a quirky PCI bus/interrupt configuration. If MPBIOS is also
defined, it'll do the job instead.

c9c95208a9 Postpone the ioapic_ih assignment a bit, since the pin number may have 
been corrected in a workaround in the meantime.

74793a8cdd Try a little harder to find PCI buses in the MPACPI code, in a (probably 
futile) attempt to get quirky ACPI implementations going.

Work around a problem with quirky MP tables for ioapic interrupt routing.

f42f32cacc Add a global_int field to the mp_intr_map structure, for use with ACPI. 
XXX should probably just use an array directly indexed by global interrupt
numbers in that case.

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.

8aca0c88d2 Add x86_pause() inline function, containing the "pause" instruction 
for i386, and nothing for amd64. Sprinkle it in various spinloops,

799347472e 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.

ab1f41a716 Add definitions (#defined out) to pass the result of the v3.x bios 
extended disk information request to the kernel.
Binary compatible with the existing code, disabled because I don't
have a system with a bios that supports the request.

bcea7d5f28 Use cached physical addresses for mbufs and clusters to save having 
to extract the physical address from the virtual.

On the ARM, also use the "read-only at MMU" indication to avoid a
redundant cache clean operation.

Other platforms should use these two as examples of how to use these
new pool/mbuf features to improve network performance.  Note this requires
a platform to provide a working POOL_VTOPHYS().

Part 3 in a series of simple patches contributed by Wasabi Systems
to improve network performance.
