Bring back Mickey's UVM anon change. Testing by thib@, beck@ and
ckuethe@ for a while. Okay beck@, "it is good timing" deraadt@.
sync
If disklabel(8) is run against unreadable media (e.g. a blank cd)
don't say "can't read master boot record". Just display an empty
disklabel. Really yucky code that needs a lot of tough love, but
marginally less confusing until then.

ok deraadt@
Calculate the disklabel checksum *after* filling in all the fields in
the disklabel.

ok deraadt@
Lookup interrupt routing info based on elroy(4) bus number.
Fix and simplify debug code that prints the interrupt routing info while
I'm there.
Handle interrupts for the record stream as well.  Recording now works.
Tested by ajacoutot@, steven@ and Will Backman.
Add a dac group init, mixer table and mixer init for the Sigmatel
codec ID 83847661 found in some Sony VAIO FE and SZ laptops.

No regressions noticed by jasper@, steven@ or Will Backman.  I've been
using it for months.
if the fd passed to atomicio/atomiciov() is non blocking, then poll() to
avoid a spin if it is not yet ready for reading/writing; ok dtucker@
"off" isn't a pointer, it's a ulong.  According to printf(3), %#lx
is equivalent to %p.

OK markus and itojun
err(3) was being called but was missing an include, and end: was
unused.

OK markus and itojun
net80211_ifstats() is called in main.c but there was no prototype.

OK markus and itojun
Remove unused variable.
Grammar-o.

OK jmc
Allow IPv6 addresses to use the CIDR notation too, no need for separate
prefixlen specification when using this form.
man page bits by jmc.

ok henning@, ``looks sane'' djm@.
Do not fatal out with ``pipe closed'' when a short read occurs on one
of our socket pairs. Instead disable listening on the pipe, terminate the
event loop, and let the parent process's SIGCHLD handler do a clean
shutdown.

from an ospfd diff by claudio, ok claudio@
Make sure perror_reply() is only called when errno is set.  When
changing perror_reply() -> reply(), increase error message detail
for ftp client.  Move free() statement to prevent errno clobbering.

OK moritz
better debug output
Pass the correct flag to sbt_start() in sbt_start_cmd()
Abort all pending ACL connections when we get an HCI command parameter
error in response to a HCI_CMD_CREATE_CON command instead of waiting
that the user aborts due to boredom.  Unfortunately, the command status
event does not include a hint to tells us which connection failed.
Mark PDE entries with PG_U and PG_M. We never need that information from the
mmu, it slightly speeds up tlb misses and according to an errata from AMD
it can actually work around a bug in the mmu.
