Reform the busdma API so that new types may be added without modifying

2013-02-12T16:57:20Z

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.

Untangle some of the confusion about what role means when it's in the FCPARAM/SDPARAM or isp_fc/isp_spi structures. This fixed a problem about seeing targets appear if you've turned off autologin and find them, or rather don't, via camcontrol rescan. MFC after: 1 month

Redo how commands handles are created and managed and implement sequence

2010-02-03T21:09:32Z

numbers and handle types in rational way. This will better protect from (unwittingly) dealing with stale handles/commands. Fix the watchdog timeout code to better protect itself from mistakes. If we run an abort on a putatively timed out command, the command may in fact get completed, so check to make sure the command we're timing it out is still around. If the abort succeeds, btw, the command should get returned via a different path.
