6087c960b5 Document the tunable kern.ipc.nsfbufs in help.common and loader.8. Small
nearby grammar fixup that saves a line of display while in the loader
(help set tunables), but reuses the line for kern.ipc.nsfbufs.

1cafed3941 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.

c141c242ac 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.

24deed1aaa - 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.

1106937d99 Remove safety belt: it is now ok to do a mtx_trylock() on a mutex you
already own.  The mtx_trylock() will fail however.  Enhance the comment
at the top of the try lock function to explain this.

35580ede37 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.

5fa8dd90f9 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.

6b869595c5 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.

all configuration of the cards that isn't in ifconfig will be removed

e1f89c222b - Create a function sched_interact_score() which decides on the

 - Use sched_interact_score() to determine the dynamic priority.
 - Define SCHED_CURR() in terms of sched_interact_score().
 - Adjust the maximum slice back down to 100ms.
 - Remove redundant clearing of ke_runq in sched_wakeup()
 - Clean up #defines and comment them.

7261f5f68e - Add a new 'flags' parameter to getblk().
- Define one flag GB_LOCK_NOWAIT that tells getblk() to pass the LK_NOWAIT
   flag to the initial BUF_LOCK().  This will eventually be used in cases
   were we want to use a buffer only if it is not currently in use.
 - Convert all consumers of the getblk() api to use this extra parameter.
