dd0b4fb6d5 Reform the busdma API so that new types may be added without modifying
every architecture's busdma_machdep.c.  It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code.  The MD busdma is then given a chance to do any final processing
in the complete() callback.

The cam changes unify the bus_dmamap_load* handling in cam drivers.

The arm and mips implementations are updated to track virtual
addresses for sync().  Previously this was done in a type specific
way.  Now it is done in a generic way by recording the list of
virtuals in the map.

ac4b6bcd17 virtio: Start taskqueues threads after attach cannot fail
If virtio_setup_intr() failed during boot, we would hang in
taskqueue_free() -> taskqueue_terminate() for all the taskq
threads to terminate. This will never happen since the
scheduler is not running by this point.

2aaf349cfc virtio_scsi: Remove duplicated lines
These must have been accidently copied from the if statement a few
lines later. Also remove parameter name from function prototype.

64d8b0b472 Fix build with PAE enabled. I doubt any code uses CAM_SCATTER_VALID or
CAM_DATA_PHYS, or they ever correctly worked, but make this build at least.
