This feature prevents the update daemon from gratuitously flushing
dirty pages associated with a mapped file-backed region of memory. The
system pager will still page the memory as necessary and the VM system
will still be fully coherent with the filesystem. Modifications made
by other means to the same area of memory, for example by write(), are
unaffected. The feature works on a page-granularity basis.
MAP_NOSYNC allows one to use mmap() to share memory between processes
without incuring any significant filesystem overhead, putting it in
the same performance category as SysV Shared memory and anonymous memory.

add support for non-pnp cards to sbc
move card identification to sbc
channel-swapping code is in sb now instead of dsp
vibra16x support is still broken, but will be fixed soon
note: sbc is now compulsory for sb cards
for pnp cards use:
device sbc0
for non-pnp cards eg:
device sbc0 at isa? port 0x240 irq 5 drq 3 flags 0x15
(hints as oldpcm)
both in addition to:

Currently we have a problem in that `dhclient' bails when configuring the
second interface as port 68 is already in use (by the `dhclient' started
for the first interface).
PR: 14810
Submitted by: n_hibma
Doing so is bogus if the loop-back interface was not configured.
Typically ``network_interfaces="auto"'' will return the list of
interfaces such that "lo0" is not first. Thus there are times when
`dhclient' configs an interface before "lo0" is configured.
Under BSD4.4, there's no need to add the above route, as it will be
automatically generated by the kernel.

second LUN to show up.
mjacob's change (which is correct) in rev 1.21 of cam_periph.c to elminiate
infinite retries of the SCSI busy status bit seems to have broken probing
of Pioneer changers that aren't already quirked.
The right way to fix this is probably to change things around so we can
guarantee 100% sequential probing of LUN-based changers even if they aren't
quirked. This should fix things for now, though.
* lockstatus() and VOP_ISLOCKED() gets a new process argument and a new
return value: LK_EXCLOTHER, when the lock is held exclusively by another

* The ASSERT_VOP_(UN)LOCKED family is extended to use what this gives them
* Extend the vnode_if.src format to allow more exact specification than
locked/unlocked.

is good for... :-)), I discovered that part of the change when mkstemps()
was brought in was missed - it was missing the termination case to make
sure it doesn't walk into the suffix. This isn't the same code OpenBSD
has, I think this is a little better as we terminate the loop in a better
spot.

There's a possibility that there are still things wrong with the

The UPAGES have not been there since Jan '96, but the hole was preserved
for BSD/OS binary compatability. This has been fixed other ways (%ebx
now has a pointer to PS_STRINGS), and the stack is nowhere near where
it used to be so this hack isn't required anymore.

for ps and gdb. Both of these have been "fixed". ps gets the p_stats
via eproc along with all the other stats, and gdb uses the regs, fpregs
etc files.
Once apon a time the UPAGES were mapped here, but that changed back
in January '96. This essentially kills my revisions 1.16 and 1.17.
The 2-page "hole" above the stack can be reclaimed now.

and fixing some major bugs.
- Add support for the v5 firmware interface, used by the DAC1164P
(tested) and AcceleRAID 352 (untested but should work). We now cover
all of the Mylex family's protocols except for v2 (used by EISA and
Alpha-compatible cards).
- Fix an accounting bug which resulted in endless 'poll still busy'
messages. In situations of high controller load the count of poll
commands could be incremented without actually successfully launching
a command. This totally removes the accounting for status poll
commnads; it was its own worst enemy.
- Add some simple reentry prevention locks to processing of the waiting
and completed command queues to prevent races which could result in
I/O being done or completed twice (both are fatal). This highlights
a need for simple locking primitives in both the UP and SMP kernels.
- Streamline the handling of command completion to reduce the amount of
redundant work being done. Remove the code which tests for commands
that have gone missing in action; nobody has ever seen one of these
and it wouldn't have worked properly anyhow.
- Handle disconnection of drives from the controller in the detach,
not shutdown method. This avoids problems flushing the cache in
a panic when a drive is mounted.
- Don't call bus_generic_detach when disconnecting drives; it doesn't
actually do anything useful.
- Increment the log message index regardless of whether we actually
retrieved one or not. If we run into a message that we can't fetch,
we don't want to spin endlessly complaining about the fact.
- Don't assume that interrupts will work when we're flushing the
controller. We may think they are enabled, but in eg. a panic
situation the controller may not be able to deliver an interrupt.
