Now Tyne boots into single user (though it's still unstable). Woohoo!

0eff671820 Also pass a type argument to comcnattach() and com_kgdb_attach(). 
comspeed() (and thus cominit()) may need this information.

d88cf589cb A few ISA sound drivers like to share dma channels, and hence deferred 
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.

To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.

All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.

0bcf529e7f Rewrite jazzio asc SCSI driver to use MI ncr53c9x and bus_dma(9) with 
BUS_DMA_ALLOCNOW flag for jazzio bus DMAC.

Tested on Soda's NEC Image RISCstation (which is an OEM of Acer PICA),
and should fix port-arc/13388.

aec10dd80c Nake return values from bounds_check_with_label() conform to the man 
page: -1 for error, 0 for EOF, 1 otherwise. Inspired by an OpenBSD commit
message, pointed out by Miod Vallat in private mail.
vax/mba/hp.c: check return value <= 0, not < 0 to be concistent with how
other places handle return values from bounds_check_with_label().

9053a4f127 NEC RISCstation 2200 (NEC-R94) doesn't have the secondary SCSI,

438b17bf15 Changes needed to bus_dma'fy fdc_jazzio.c and asc.c: 
Modify jazz_bus_dmamap_create() to allocate jazz dmatlb
 if BUS_DMA_ALLOCNOW flag is specified and nsegment is 1.
 In this case, jazz_bus_dmamap_load() just call
 jazz_dmatlb_map_va() to map CPU VA space into jazzio
 VA space with pre-allocated TLB entries (like dma.c does).
 bus_dmamap_load_{mbuf,uio,raw} functions are not allowed
 if dmamap is created with BUS_DMA_ALLOCNOW flag.
 (i.e. ALLOCNOW is valid only for linear buffers.)
