cc06ca6693 * Add the "VIPER 150/21531" to quirk list (ST_Q_SENSE_HELP). 
* Double timeout on tape position commands to 30 minutes. Some units
  seem capable of taking that much time.

8e8eed4ba7 Create RX DMA maps with ALLOCNOW. These maps are essentially always 
loaded, and recovering from a resource shortage error is much harder
in the receive case.

c2f8ffc062 reserve some pages for the kernel, and some more especially 
for the pagedaemon allocating from kmem_object.  this should
prevent from the pagedaemon running out of memory and deadlocking.

5942e0ff3d initial implementation of OFW ISA bus code and attachments for a few 
devices.  Still a bit rough, but works well enough.  Requires a bunch of
machine-dependent glue (since this is, in effect, a MI bus bridge).

e08a44b196 - Perform all necessary bus_dmamap_sync() operations. 
- Greatly simplify allocation and DMA mapping of the mailbox and ccbs.
- Be more robust against resource shortage errors, and report errors better.

8098a443f0 A version of the de driver which does bus_dma. Note that it has not been 
tested on any other platform other than i386.  Use of bus_dma(9) can be
turned by defining TULIP_BUS_DMA_NOTX and TULIP_BUS_DMA_NORX.  These allow
one to determine if the problem is in the transmit or receive path.
A problem reported by mycroft is also fixed.

a66f53e128 Add M_SETCTX and M_GETCTX. These overload m_pkthdr.rcvif so drivers can 
use it as a context field.

c0c3c30be3 When allocating bus space in bus_space_alloc(), use EX_FAST to find 
the first fit in the map.  The previous behavior violated the principle
of least surprise (especially annoying when you're debugging space allocation
problems).  Suggested by Chris Demetriou.
