wasteful, but better than clobbering the variables below the stack.
About 300 bytes of variables were clobbered when I examined double
faults using ddb. Perhaps a page that is known not to be accessed by
the double fault handler could be used. Such pages are not easy to
find, since the double fault handler calls panic() which calls sync()
and possibly dumpsys().
part of the DMA channel 0 address and wasn't random in the intended
way.

Disable interrupts while reading the clock. This probably isn't
important (allowing interrupts probably increased randomness in
the usual case).
Removed __i386__ ifdef. This file is in an i386 directory and has
other i386 dependencies.
unintentionally committed):
- the fifo was completely disabled for low speeds. Apart from being
unnecessarily inefficient, this invalidated com->tx_fifo_size.
- `ftl' became a bogus name.
- the 16650 probe breaks the COM_NOFIFO() case and has other bugs
(disabled, not fixed).
Fixed bogus change of the fifo settings for the non-speed of 0. This
bug made the above fifo bug occur even at non-low speeds.
Fixed the modes of the cua devices. It isn't possible to set the uid
and gid correctly since the kernel can't know who uucp.dialer is.
Register the devswitch at device attach time. SYSINIT() is not
the right way to initialize devswitches (if anything :->).
Eventually, the devswitch should be deregistered at device detach
and/or unload time and reregistered at device attach time ... Then
some com->gone tests could be removed.
Cleaned up some other recent changes.
than separate ip_v and ip_hl members. Should have no effect on current code,
but I'd eventually like to get rid of those obnoxious bitfields completely.
redistribute a few last routines to beter places and shoot the file
I haven't act actually 'deleted' the file yet togive people time

so I'll remove it then..
it's now empty.
makes the question of a USL copyright rather moot.
about decoding trap/syscall/interrupt frames and generally works better
than the previous stuff.
Removed some special (incorrect) frobbing of the frame pointer that
was messing some things up with the new traceback code.
others: start to populate the link-layer branch of the net mib, by
moving ARP to its proper place. (ARP is not a protocol family, it's an
interface layer between a medium-access layer and a protocol family.)
sysctl(8) needs to be taught about the structure of this branch, unless
Poul-Henning implements dynamic MIB exploration soon.
overflows.
It sure would be nice if there was an unmapped page between the PCB and
the stack (and that the size of the stack was configurable!). With the
way things are now, the PCB will get clobbered before the double fault
handler gets control, making somewhat of a mess of things. Despite this,
it is still fairly easy to poke around in the overflowed stack to figure
out the cause.
Unstaticize a function in scsi/scsi_base that was used, with an undocumented
option.
My last count on the LINT kernel shows:
Total symbols: 3647
unref symbols: 463
undef symbols: 4
1 ref symbols: 1751
2 ref symbols: 485
Approaching the pain threshold now.
