no ports are active, provided there are no polled ports and no
`LOSESOUTINTS' ports. Do a little more in the interrupt handler instead.
This is a little less efficient if there are are many active ports but
a little more efficient otherwise. Polled ports are ones with no irq
specified (as before). `LOSESOUTINTS' ports are ones with 0x08 set in
their config flags. Unless this flag is set, it will now take up to one
second to recover from lost output interrupts, if any. Some 8250s and
16450s lose output interrupts.
Improve output buffering: copy the clist buffer to 2 linear buffers if
necessary and possible instead of to 1. Handle an arbitrary queue of
buffers in the interrupt handler. Check for waking up sleepers after
copying characters out of the clist buffer instead of before.

For the LKM_E_LOAD case of the DISPATCH() macro, use lkmexists() to
make sure we don't have another instance the module we're trying to
load already loaded _before_ calling the module's load() function.
If lkmexists() returns true, return EEXIST without trying to load
the module.
For most types of modules, the individual dispatch functions in the
kernel check for duplicated modules, but for LM_MISC we can't trust
the module to do the checks itself. Currently, the kernel does
do an lkmexists() check on LM_MISC modules, but not until after
the module's load() function has been called, which is too late
for it to do any good. If the load() function does irreversible
things to the kernel, the belated lkmexists() check forces an
unload() and a crash.

Fix one such THING in code to match comment.

Uniformize whitespace.
Uniformize case in hex digits.
This file is very incomplete. In particular, it doesn't mention any
network cards. This doesn't matter much for the base addresses, but
it means that the comments about which addresses are free are mostly
bogus. The i/o sizes are unreliable because of split address ranges
for many devices (VGA, wd). The i/o sizes are incomplete. In
particular, there are no sizes for SCSI controllers. The bt driver
still returns a truth value instead of a size.
is an ambiguity in the NFS version 2 protocol.
VREG should be taken literally as a regular file. If a
server intents to return some type information differently
in the upper bits of the mode field (e.g. for sockets, or
FIFOs), NFSv2 mandates fa_type to be VNON. Anyway, we
leave the examination of the mode bits even in the VREG
case to avoid breakage for bogus servers, but we make sure
that there are actually type bits set in the upper part of
fa_mode (and failing that, trust the va_type field).
NFSv3 cleared the issue, and requires fa_mode to not
contain any type information (while also introduing sockets
and FIFOs for fa_type).
The fix has been tested against a variety of NFS servers.
It fixes problems with the ``Tropic'' NFS server for Windows,
while apparently not breaking anything.

- the major number wasn't checked, so accesses beyond the end of bdevsw[]
were possible. Bogus major numbers are easy to get because `sysctl -w'
doesn't handle dev_t's reasonably - it doesn't convert names to dev_t's
and it converts the number 1025 to the dev_t 0x35323031.
- Driver d_psize() functions return -1 to indicate error ENXIO or ENODEV
(the interface is too braindamaged to say which). -1 was interpreted
as a size and resulted in the bogus error ENOSPC.
- it was possible to set the dumpdev for devices without a d_psize()
function. This is equivalent to setting the dumpdev to NODEV except
it confuses sysctl.
- change a 512 to DEV_BSIZE. There is an official macro dtoc() for
converting "pages" to disk blocks but it is never used in /usr/src/sys.
There is much confusion between PAGE_SIZE sized pages and NBPG sized
pages. Maxmem consists of both.
Not fixed:
- there is nothing to invalidate the dumpdev if the media goes away.
This reduces the benefits of the early calculation of dumplo. Bounds
checking in the dump routines is relied on to reduce the risk of
damage and little would be lost by relying on the dump routines to
calculate dumplo.
- no attempt is made to stay away from the start of the device to
avoid clobbering labels.
