carrier-detect transitions, as described in the xntp documentation.
Use the same value as FreeBSD (88) for binary compatibility.
Should be implemented in lowest-level interrupt handler of serial drivers.
of the old boot area so that 'disklabel -r -w' won't clobber anything,
be sure to seek to the offset of the boot area (like readlabel() does).
Otherwise, if the machine has code which looks up machine-dependent label
bits, the offset read from will be incorrect, and disklabel will end up
secretly replacing the boot area with other data (which probably doesn't
look like a boot block). The only port this currently affects is
NetBSD/arm32, because it's the only one of the three ports that use
NUMBOOT > 0 that has MD label grovelling code.
pvlists if they were entered by the fault routine. in this case
we had better call pmap_remove to clear out the pventry structures.
appears to fix some pvlist releated panics people have seen with pmap.new.
Replace all DS5000_* and DS3100 ifdefs with ifdefs on DEC_ options.
* Use MI declarations, not pmax-specific, in model-specific init
that uses baseboard (ioasic) registers.
* Further cleanup of machdep.c. Clock-tick still needs more thought.
* Use 'ibus' names for 3100 baseboard devices in MI code.
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
(based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
support for models of MIPS cpus. They differ more than Alphas).
* For each supported model of DECstation, create a separate file
with the support for that model. Use model codenames, since
support is really baseboard-specific and CPU daugherboards can change.
Move code from machdep.c and pmax_trap.c,
Add sysconf (nee "cpuconf") support.
* Rename model-specific functions to match sysconf names.
* Clean up autoconf.c. Use platform callbacks.
* Retire pmax_trap.c.
Leaves I/O bus configuration and console configuration untouched.
the kernel on most platforms, including all of the entry-level platforms.
2. Kill the comments and options for load address selection.
3. Kill the default -g.
Write an intro.4, closing PR#3978
Fix some typos, some unclear english, diddle the nroff a bit.
One outstanding issue: plip.4 has a tbl(1) table in it, but the Makefile
does nothing to format it right.
