Use sys/cdefs.h __CONCAT3

Provide PRIxBUSADDR, PRIxBUSSIZE, PRIuBUSSIZE, and PRIxBSH for all arches
to follow arm and (generic) mips.

Change old-style function defintions to C89 prototypes.

Remove all the __P() from sys (excluding sys/dist)

i386 and amd64 GENERIC and sys still build.

Remove clause 3 and 4 from TNF licenses

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

add a pair of new bus_dma(9) functions:
int _bus_dmatag_subregion(bus_dma_tag_t tag,

bus_addr_t max_addr,

int flags)

add a pair of new bus_dma(9) functions:
int _bus_dmatag_subregion(bus_dma_tag_t tag,
bus_addr_t min_addr,
bus_addr_t max_addr,
bus_dma_tag_t *newtag,
int flags)
void _bus_dmatag_destroy(bus_dma_tag_t tag)

that allow a (normally broken/limited) device to restrict the bus address
range it can talk to. this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.

all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several
people on tech-kern.

XXX: bus_dma(9) needs an update still.

Tweak bus_space_barrier(9) macro to appease

warnings by gcc4.

Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

Add a dm_maxsegsz public member to bus_dmamap_t. This allows a user of the API
to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz

bus_dmamap_create when the dmamap is unloaded.

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.

Introduce BUS_DMA_NOCACHE, and bus_dmamem_map() of i386 supports it.

Make sure that private DMA flags don't overlap with standard DMA flags;
start these at 0x10000 to leave room for an increase in the latter.

Merge the thorpej-mips-cache branch onto the trunk. This is an
overhaul of how caches are handled for NetBSD's MIPS ports.

bus_space_mmap support based on -arc implementation

Add BUS_DMA_READ and BUS_DMA_WRITE flags, that hint the back-end
at dmamap load time that the mapping will be used for a unidirectional
transfer of the specified direction.

Re-implement bus_space(9) functions:
- Correctly handle striding of data
- Better support for endian neutral access
- Correctly implement _stream variants of bus_space functions that can
byte swap. This reverses the automatic byte swapping done in hardware
for 16 bit ISA bus cards
