18ef8344b4 - Further simplify lookup; Force all filesystems to relock in the DOTDOT
case.  There are bugs in some which didn't unlock in the ISDOTDOT case
   to begin with that need to be addressed seperately.  This simplifies
   things anyway.
 - Fix relookup() to prevent it from vrele()'ing the dvp while the vp
   is locked.  Catch up to other lookup changes.

f0c1dee27f The latest release of the FreeBSD driver (twa) for
3ware's 9xxx series controllers.  This corresponds to
the 9.2 release (for FreeBSD 5.2.1) on the 3ware website.

Highlights of this release are:

1. The driver has been re-architected to use a "Common Layer"
    (all tw_cl* files), which is a consolidation of all OS-independent
    parts of the driver.  The FreeBSD OS specific portions of the
    driver go into an "OS Layer" (all tw_osl* files).
    This re-architecture is to achieve better maintainability, consistency
    of behavior across OS's, and better portability to new OS's (drivers
    for new OS's can be written by just adding an OS Layer that's specific
    to the OS, by complying to a "Common Layer Programming Interface" API.

2. The driver takes advantage of multiple processors.

3. The driver has a new firmware image bundled, the new features of which
   include Online Capacity Expansion and multi-lun support, among others.
   More details about 3ware's 9.2 release can be found here:
   http://www.3ware.com/download/Escalade9000Series/9.2/9.2_Release_Notes_Web.pdf

Since the Common Layer is used across OS's, the FreeBSD specific include
path for header files (/sys/dev/twa) is not part of the #include pre-processor
directive in any of the source files.  For being able to integrate twa into
the kernel despite this, Makefile.<arch> has been changed to add the include
path to CFLAGS.

a08d773359 Dot the i's:
1  Move the debug.clock_adjust_* sysctls to debug.clock.adjust_* to
   make it easier to get only the clock statistics.
2  Make the sysctls read-only [suggested by Marius].
3  When determining the new clock adjustment, we checked for an error
   either larger than 12.5% or smaller than 12.5%. We left out an error
   of exactly 12.5%. For errors larger than 12.5% we adjust the clock
   reload value in such a way that the next clock interrupt would be
   early (as in premature). For errors less than 12.5% we stopped the
   adjustment.
   The current algorithm doesn't benefit from excluding an error of
   exactly 12.5%. Change the code to stop adjusting the clock if the
   error is *not* larger than 12.5% [suggested by Marius].

d02239a3af Create new i386 windows/bsd thunking layer, similar to the amd64 thunking
layer, but with a twist.

The twist has to do with the fact that Microsoft supports structured
exception handling in kernel mode. On the i386 arch, exception handling
is implemented by hanging an exception registration list off the
Thread Environment Block (TEB), and the TEB is accessed via the %fs
register. The problem is, we use %fs as a pointer to the pcpu stucture,
which means any driver that tries to write through %fs:0 will overwrite
the curthread pointer and make a serious mess of things.

To get around this, Project Evil now creates a special entry in
the GDT on each processor. When we call into Windows code, a context
switch routine will fix up %fs so it points to our new descriptor,
which in turn points to a fake TEB. When the Windows code returns,
or calls out to an external routine, we swap %fs back again. Currently,
Project Evil makes use of GDT slot 7, which is all 0s by default.
I fully expect someone to jump up and say I can't do that, but I
couldn't find any code that makes use of this entry anywhere. Sadly,
this was the only method I could come up with that worked on both
UP and SMP. (Modifying the LDT works on UP, but becomes incredibly
complicated on SMP.) If necessary, the context switching stuff can
be yanked out while preserving the convention calling wrappers.

(Fortunately, it looks like Microsoft uses some special epilog/prolog
code on amd64 to implement exception handling, so the same nastiness
won't be necessary on that arch.)

The advantages are:

- Any driver that uses %fs as though it were a TEB pointer won't
  clobber pcpu.
- All the __stdcall/__fastcall/__regparm stuff that's specific to
  gcc goes away.

Also, while I'm here, switch NdisGetSystemUpTime() back to using
nanouptime() again. It turns out nanouptime() is way more accurate
than just using ticks(). On slower machines, the Atheros drivers
I tested seem to take a long time to associate due to the loss
in accuracy.

c5cb8d604c Fix the output ports on the AD1988 codec. From the submitter:
Affects to people WITH an AD1888 codec, the system will output to the port
labeled "speaker" instead of microphone.  System will work the same in
multiple operating systems.

If people are currently using their systems with this codec they will need
to swap their output ports.

I have _not_ checked audio input or line input (basically, I have checked
nothing other than line-out).

I believe this is an appropriate change, it makes us consistent with
documentation, and other operating systems.  Furthermore, this feature
(playing) is the vast majority of sound activities, so if this makes is
right for playback and wrong for recording... playback is more important,
and we can fix recoding in the future without worries of screwing people
again in the future (since we'll be "right" on the playback).

f97c3df18d Suspend all other threads in the process while generating a core dump.
The main reason for doing this is that the ELF dump handler expects
the thread list to be fixed while the dump header is generated, so an
upcall that occurs at the wrong time can lead to buffer overruns and
other Bad Things.

Another solution would be to grab sched_lock in the ELF dump handler,
but we might as well single-thread, since the process is about to die.
Furthermore, I think this should ensure that the register sets in the
core file are sequentially consistent.

d3b78f7337 - If we vrele() a dvp while the child is locked we can potentially deadlock
when vrele() acquires the directory lock in the wrong order.  Fix this
   via the following changes:
 - Keep the directory locked after VOP_LOOKUP() until we've determined
   what we're going to do with the child.  This allows us to remove the
   complicated post LOOKUP code which determins whether we should lock or
   unlock the parent.  This means we may have to vput() in the appropriate
   cases later, rather than doing an unsafe vrele.
 - in NDFREE() keep two flags to indicate whether we need to unlock vp or
   dvp.  This allows us to vput rather than vrele in the appropriate
   cases without rechecking the flags.  Move the code to handle dvp after
   we handle vp.
 - Remove some dead code from namei() that was the result of changes to
   VFS_LOCK_GIANT().

o Drop the fragment if maxfragsperpacket == 0, no chances we
will be able to reassemble the packet in future.
