structures can thus be misaligned for DMA when declared on stack.
The current atapi code accepts the misaligned dma's only screw's them up.
This small patch disables DMA for the rare transactions that are
misaligned. Note that all bulk-transfers are aligned due to page sizes.

SMBios detection and mapping to bios32.c, also from OpenBSD (for now this
is only compiled in if ipmi(4) is configured). The sensors and watchdog are
accessible though envsys(4).
Works on i386; some work is needed on amd64 to access the BIOS. It would
eventually work on Xen if the SMBios is accessible (to be tested).
and if ALTQ and pf are both enabled, it leads to compile errors. So,
change all tests for ALTQ to ALTQ_NEW, which won't be defined.
This allows simultaneous compilation of pf and ALTQ and is a temporary
measure before the peter-altq brach is merged.
Tested and approved by Peter Postma.
driver uses the board's DMA system, uses the machine-independent WD33C93
driver, works on NetBSD/acorn26, and doesn't share a name with six other
machine-dependent SCSI drivers. Not tested on acorn32, but it seems to
work tolerably well on my A540.
- make sun3 port use common sun68k files as much as possible
- add temporary options _SUN2_ in std.sun2 until sun3 can share all
sun68k files (autoconf.c and isr.c are not yet)
- move sun68kvme declaration temporary as well from files.sun68k to files.sun2
- rename and move sun68k_find_prom_map() function to MD sources since it
can't be shared with sun3
- add bus tag members to struct confargs and initilize them where appropriate
XXX1: MD bus_dma(9) backends are not implemented (yet).
XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.
It uses an authorization wrapper per device class on the system to
ensure type-safety.
For now, it supports only terminal (TTY) devices, and has two actions
for them: "open terminal" and "privileged set". Sample usage has been
added to i386 and hp300 code for reference.
Update documentation.
