thorpej babefc5331 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.

simonb 889c658b5b Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

drochner 8eb798e603 define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that
device accesses are idempotent (but should not be cached by the CPU)

cgd 7c02d93c04 nuke current definitions provided by __BUS_SPACE_COMPAT_OLDDEFS.
I'll do what I can to make new ones soon.  8-)

drochner 76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context,
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)
