that a lock is held whilst the allocations are made (M_WAITOK -> M_NOWAIT).

3e6967b30c Raise the default value of TTYHOG from 1 kB to 8 kB. Since TTYHOG is
an administrative limit on the size of tty/pty input buffers, this is
mostly an inconsequential change.  (slti(4) will allocate an 8 kB
static buffer instead of a 1 kB buffer due to a hack in the driver.)
The increase happens to kludge around a lame limitation of syscons,
which does not allow one to paste more than TTYHOG bytes.

d4ee62b07a Fix threaded applications on ia64 that are linked dynamicly. We did
not save (restore) the global pointer (GP) in the jmpbuf in setjmp
(longjmp) because it's not needed in general. GP is considered a
scratch register at callsites and hence is always restored after a
call (when it's possible that the call resolves to a symbol in a
different loadmodule; otherwise GP does not have to be saved and
restored at all), including calls to setjmp/longjmp. There's just
one problem with this now that we use setjmp/longjmp for context
switching: A new context must have GP defined properly for the
thread's entry point. This means that we need to put GP in the
jmpbuf and consequently that we have to restore is in longjmp.
This automaticly requires us to save it as well.

When setjmp/longjmp isn't used for context switching, this can be
reverted again.

cf2b37334b Don't cast an int to a pointer type without (possibly) widening the
integral type to the size of a pointer type when it's known that the
cast is valid. On ia64 such casts are generally bad news and has led
us (=peter :-) to make such casts fatal. By casting to intptr_t
before casting to a pointer type, this now compiles cleanly in LP64
architectures. Note that the final cast has been changed to void*
(instead of siginfo_t*) to make it explicit that we're not trying to
pass a siginfo_t pointer but rather trying to pass an int when the
prototype says it should be a pointer.

55f069454e ABI breaker: Move the J_SIGMASK field in the jmpbuf before
the J_SIG0 field. While here, rename J_SIG0 to J_SIGSET and
remove J_SIG1. The main reason for this change is that the
128-bit sigset_t is now aligned on a 16-byte boundary, which
allows us to use 16-byte atomic loads and stores on CPUs that
support it. The removal of J_SIG1 is done to avoid confusion:
it is never accessed and should not be. Renaming J_SIG0 to
J_SIGSET is the icing on the cake that's better done now than
later.

04e28d5a81 Update netisr handling; Each SWI now registers its queue, and all queue
drain routines are done by swi_net, which allows for better queue control
at some future point.  Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

45fcac94f4 Bah, fix a bogon in the last commit: get the sense of a compare test right
so that we allow a sleepable lock to be acquired with Giant held rather
than allowing a sleepable lock to be acquired with anything but Giant held.

bfd7640850 - Hold the buf lock while manipulating and inspecting its fields.
- Use gbincore() and not incore() so that we can drop the vnode interlock
   as we acquire the buflock.
 - Use GB_LOCK_NOWAIT when getting bufs for read ahead clusters so that we
   don't block on locked bufs.
 - Convert a while loop to a howmany() that will most likely be faster on
   modern processors.  There is another while loop divide that was left
   near by because it is operating on a 64bit int and is most likely faster.
 - Cleanup the cluster_read() code a little to get rid of a goto and make
   the logic clearer.

c5a53306ce A small overhaul of witness:
- Add a comment about special lock order rules and Giant near the top of
  subr_witness.c.  Specifically, this documents and explains the real lock
  order relationship between Giant and sleepable locks (i.e. lockmgr locks
  and sx locks).  Basically, Giant can be safely acquired either before or
  after sleepable locks and the case of Giant before a sleepable lock is
  exempted as a special case.
- Add a new static function 'witness_list_lock()' that displays a single
  line of information about a struct lock_instance.  This is used to
  make the output of witness messages more consistent and reduce some code
  duplication.
- Fixup a few comments in witness_lock().
- Properly handle the Giant-before-sleepable-lock lock order exception in
  a more general fashion and remove the no longer needed LI_SLEPT flag.
- Break up the last condition before assuming a reversal a bit to try
  and make the logic less confusing in witness_lock().
- Axe WITNESS_SLEEP() now that LI_SLEPT is no longer needed and replace it
  with a more general WITNESS_WARN() macro/function combination.
  WITNESS_WARN() allows you to output a customized message out to the
  console along with a list of held locks.  It will optionally drop into
  the debugger as well.  You can exempt a single lock from the check by
  passing it in as the second argument.  You can also use flags to specify
  if Giant should be exempt from the check, if all sleepable locks should
  be exempt from the check, and if witness should panic if any non-exempt
  locks are found.
- Make the witness_list() function static.  Other areas of the kernel
  should use the new WITNESS_WARN() instead.

f78f351da3 Miscellaneous cleanups to _mtx_lock_sleep():
- Declare some local variables at the top of the function instead of in a
  nested block.
- Use mtx_owned() instead of masking off bits from mtx_lock manually.
- Read the value of mtx_lock into 'v' as a separate line rather than inside
  an if statement for clarity.  This code is hairy enough as it is.

3b2bb7e47b Properly assert that mtx_trylock() is not called on a mutex we already
owned.  Previously the KASSERT would only trigger if we successfully
acquired a lock that we already held.  However, _obtain_lock() fails to
acquire locks that we already hold, so the KASSERT was never checked in
the case it was supposed to fail.
