mapping to 4KB page mappings when the specified attribute change only
applies to a portion of the 2MB page. Previously, in such cases,
pmap_change_attr() gave up and returned an error.

- Check if panicstr isn't set, if it is ignore the lock. This helps to avoid
confusion, because lockmgr is a no-op when panicstr isn't NULL, so
asserting anything at this point doesn't make sense and can just race with
other panic.

This allows one to set multiple p2p links to the same place
and select which to use by having each in different FIBS.
turns out some devices do this and since we otherwise validate the station
is associated and don't use the aid for anything being lenient here allows
them to function

describes the minimum versions of each feature and each chipset type
supported by this driver. Basically, unless you have a very modern
version of firmware on a Prism card, you won't be able to use these
cards for much on modern networks that have any kind of protection
enabled, except for the few WEP-only stranglers that appear at some
conferences...
This gives significant performance improvements when many raw sockets used.
Benchmarks of mpd handeling 1000 simultaneous PPTP connections show up to 50%
performance boost. With higher number of connections benefit becomes even
bigger. PopTop snd others should also get some benefits.
the beginning. There's a race in the shared interrutp case. If
another interrupt happens after the interrupt is setup, then we'd try
to lock an uninitialized mutex. In addition, if we bailed out due to
a too old version of firmware, we'd leave the interrupt enabled with
all the fun that ensues....

Yes, it means some old bugs returned, like not setted rs_stired = 1 in
arc4random_stir(3) causing double stirring.
The ttyinfo() routine generates the fancy output when pressing ^T. Right
now it is stored in tty.c. In the MPSAFE TTY code it is already stored
in tty_info.c. To make integration of the MPSAFE TTY code a little
easier, take the same approach.
This makes the TTY code a little bit more readable, because having the
proc_*/thread_* routines in tty.c is very distractful.

When I turned sgtty into a binary-only interface (last month), I added
this explicit #error to the header file, to make sure nobody forgot to
remove the header file after updating world.
I think it is now a good moment to remove this header file.

The kbd, kbdmux, ugen and uhid drivers included <sys/tty.h>, because
they needed clists, which have been moved to <sys/clist.h> some time
ago. In the MPSAFE TTY branch, <sys/tty.h> does not include
<sys/clist.h>, which means we have to teach these drivers to include
this header file directly.

We're very lucky, because the flags used by our TIOCPKT implementation
are the same as flags used by Linux. We can safely enable TIOCPKT,
assuming EXTPROC is not used.
TIOCSPTLCK is used by unlockpt(). Because we don't need unlockpt() in
our implementation, make this ioctl a no-op.

but removed too much, breaking the build in other places instead. Now
that the ipfilter issue has been fixed (or hacked around), address the
second issue by restoring r180755, with one small change. I don't feel
comfortable using assert(3) in a header that will be included in userland
code that may or may not already have an assertion mechanism in place,
so KASSERT() evaluates to a no-op in the !_KERNEL case.
