Add collation sequence for no_NO. The same sequence applies to nb_NO
and nn_NO, which are symlinked to no_NO.
The patch in the PR contained a number of errors apparently based on
(sometimes incorrect) pronunciation; for instance, v and w are
distinct letters and should be collated in that order, even if they
are pronounced the same, while <u:> should be collated with u, even
though it is often mispronounced as y. For lack of a solid reference,
I have taken sv_SE and simply changed the last three letters of the
alphabet.
Fix a few bugs with the _gettemp() routine which implements mkstemp(),
mkstemps(), and mkdtemp().
- Add proper range checking for the 'slen' parameter passed to mkstemps().
- Try all possible permutations of a template if a collision is encountered.
Previously, once a single template character reached 'z', it would not wrap
around to '0' and keep going until it encountered the original starting
letter. In the edge case that the randomly generated starting name used
all 'z' characters, only that single name would be tried before giving up.

When choosing a CPU for a thread in a cpuset, prefer the last CPU that the
thread ran on if there are no other CPUs in the set with a shorter per-CPU
runqueue.
Don't attempt authentication at all if it has been disabled via '-a off'.
This works around a bug in HP-UX's telnet client and also gives a much
saner user experience when using FreeBSD's telnet client.

Implement support for cpusets in the 4BSD scheduler.
- When a cpuset is applied to a thread, walk the cpuset to see if it is a
"full" cpuset (includes all available CPUs). If not, set a new
TDS_AFFINITY flag to indicate that this thread can't run on all CPUs.
When inheriting a cpuset from another thread during thread creation, the
new thread also inherits this flag. It is in a new ts_flags field in
td_sched rather than using one of the TDF_SCHEDx flags because fork()
clears td_flags after invoking sched_fork().
- When placing a thread on a runqueue via sched_add(), if the thread is not
pinned or bound but has the TDS_AFFINITY flag set, then invoke a new
routine (sched_pickcpu()) to pick a CPU for the thread to run on next.
sched_pickcpu() walks the cpuset and picks the CPU with the shortest
per-CPU runqueue length. Note that the reason for the TDS_AFFINITY flag
is to avoid having to walk the cpuset and examine runq lengths in the
common case.
- To avoid walking the per-CPU runqueues in sched_pickcpu(), add an array
of counters to hold the length of the per-CPU runqueues and update them
when adding and removing threads to per-CPU runqueues.
Export the hardware type (as number and name), the secondary firmware
revision and (on Prism cards) the primary firmware revision via

Add a check for 1GB page mappings to pmap_change_attr() so that it fails

1GB page mappings.)
Enhance pmap_change_attr(). Use pmap_demote_pde() to demote a 2MB page
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.
- Move vp test for beeing NULL under IGNORE_LOCK().
- 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.

Move ttyinfo() into its own C file.
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.

pjd@'s r180759 was intended to revert r180755 due to ipfilter breakage,
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.

For unfathomable reasons, ipfilter abuses kernel data structures for its
own purposes. To pull this off, it defines _KERNEL before including the
headers where these structures are defined. This leads to no end of
trouble when some of these headers, or other headers that they include,
change, as demonstrated by r180755.
The quick fix in this particular case is to define _WANT_FILE instead of
_KERNEL, conditional on __FreeBSD__. A better long-term fix is left as
an exercise to the reader.
Further refine the probe order of devices to more closely match the previous
behavior. Specifically, probe Host-PCI bridges in the order they are
encountered in the tree. For CPUs, just use an order of 100000 and assume
that no Host-PCI bridges will be more than 10000 levels deep in the
namespace. This fixes an issue on some boxes where the HPET timer stopped
attaching.
The ffs_balloc_ufs{1,2} functions call bdwrite() while having several
vnode buffers locked at once. In particular, there are indirect buffers
among locked ones. The bdwrite() may start the flushing to keep dirty
buffer list at the bounds. If any buffer on the dirty list requires
translation from logical to physical block number, code may ends up
trying to lock an indirect buffer already locked in ffs_balloc_ufsX.
Prevent the bdflush() activity when several buffers are locked at once
by setting the TDP_INBDFUSH for the problematic code blocks.

Unbreak cc -pg support on i386. In gcc 4.2, %ecx is used as the arg pointer
when stack realignment is turned on (it is ALWAYS on for main), however

This fix changes mcount() to preserve %ecx.

Do the pargs_hold() on the copy of the pointer to the p_args of the
child process immediately after bulk bcopy() without dropping the

Since process is not single-threaded when forking, dropping and
reacquiring the lock allows an other thread to change the process title
of the parent in between, and results in hold being done on the invalid
pointer. The problem manifested itself as the double free of the old
p_args.
