Fix a handful of issues with via agp support.
* Read the pci capability register to identify AGP 3 support
* Add missing smaller aperture sizes for AGP3 chips.
* Fix the aperture size calculation on AGP2 chips.
All sizes between 32M and 256M reported as 256M.
* Add \n to error string.
o Add PCI ID for BCM 5756.
o Don't enable BGE_FLAG_BER_BUG on both 5722 and 5756, and based
on their PCI IDs rather than their chip IDs.

Adapt OpenBSD pf's "sloopy" TCP state machine which is useful for Direct
Server Return mode, where not all packets would be visible to the load
balancer or gateway.
This commit should be reverted when we merge future pf versions. The
benefit it would provide is that this version does not break any existing
public interface and thus won't be a problem if we want to MFC it to
earlier FreeBSD releases.

The devices that supported EVFILT_NETDEV kqueue filters were removed in
r195175. Remove all definitions, documentation, and usage.
The change of function signature for vlan_link_state() was not merged to
maintain the ABI.
Add multichannel (4.0, 5.1 and 7.1) playback support.
Stereo stream is no more duplicated to all ports. If you loose sound, check
you are using right connectors. Front speakers connector is usually green,
center/LFE - orange, rear - black, side - gray.
Make default recording source choosing more intelligent.
Change default recording level from 0 to 75.
It should increase chances for things to work just out of the box.
- Fix several off-by-one errors when using MAXCOMLEN. The p_comm[] and
td_name[] arrays are actually MAXCOMLEN + 1 in size and a few places that
created shadow copies of these arrays were just using MAXCOMLEN.
- Prefer using sizeof() of an array type to explicit constants for the
array length in a few places.
- Ensure that all of p_comm[] and td_name[] is always zero'd during
execve() to guard against any possible information leaks. Previously
trailing garbage in p_comm[] could be leaked to userland in ktrace
record headers via td_name[].
Add a facility for associating optional descriptions with active interrupt
handlers. This is primarily intended as a way to allow devices that use
multiple interrupts (e.g. MSI) to meaningfully distinguish the various
interrupt handlers.
- Add a new BUS_DESCRIBE_INTR() method to the bus interface to associate
a description with an active interrupt handler setup by BUS_SETUP_INTR.
It has a default method (bus_generic_describe_intr()) which simply passes
the request up to the parent device.
- Add a bus_describe_intr() wrapper around BUS_DESCRIBE_INTR() that supports
printf(9) style formatting using var args.
- Reserve MAXCOMLEN bytes in the intr_handler structure to hold the name of
an interrupt handler and copy the name passed to intr_event_add_handler()
into that buffer instead of just saving the pointer to the name.
- Add a new intr_event_describe_handler() which appends a description string
to an interrupt handler's name.
- Implement support for interrupt descriptions on amd64, i386, and sparc64 by
having the nexus(4) driver supply a custom bus_describe_intr method that
invokes a new intr_describe() MD routine which in turn looks up the
associated interrupt event and invokes intr_event_describe_handler().

Extra parantheses to keep certain compilers happy.

Fix for a cxgb(4) panic. cxgb_ioctl can be called by the IP and IPv6
layers with non-sleepable locks held. Don't (potentially) sleep in
those situations.
r202678:
Complain if freelist queue sizes are significantly less than desired.
Don't free mbuf chains when bge(4) fails to collapse the mbuf
chains. This part of code is to enhance performance so failing the
collapsing should not free TX frames. Otherwise bge(4) will
unnecessarily drop frames which in turn can freeze the network
connection.

Add check for fiber mode for BCM5714 PHY. This PHY supports both
copper and fiber interfaces over GMII so an explicit check is
necessary to know whether it was configured for fiber interface.

For controllers that has dual mode PHY(copper or fiber) interfaces
over GMII, make sure to enable GMII. With this change brgphy(4) is
used to handle the dual mode PHY. Since we still don't have a sane
way to pass PHY specific information to mii(4) layer special
handling is needed in brgphy(4) to determine which mode of PHY was
configured in parent interface.

Usually these controllers are able to automatically decode command code to
get required command protocol. But they have no idea about new commands,
such as DATA SET MANAGEMENT (TRIM). As soon as this info any way provided
by CAM, give controller specific instructions.
Clear all ports interrupt status bits in single write. Clearing one by one
causes additional MSIs messages sent if several ports asked for attention
same time. Time window before clearing is not important, as these interrupts
are level triggered by interrupt source.
Add BIO_DELETE support to ada(4):
- For SSDs use TRIM feature of DATA SET MANAGEMENT command, as defined by
ACS-2 specification working draft.
- For CompactFlash use CFA ERASE command, same as ad(4) does.
With this patch, `newfs -E /dev/ada1` was able to restore write speed of
my heavily weared OCZ Vertex SSD (firmware 1.4) up to the initial level
for the most part of it's capacity.
I have no idea whether it is normal, but for some reason it takes 200ms
to handle any TRIM command on this drive, that was making delete extremely
slow. But TRIM command is able to accept long list of LBAs and the length of
that list seems doesn't affect it's execution time. Implemented request
clusting algorithm allowed me to rise delete rate up to reasonable numbers,
when many parallel DELETE requests running.
In current code, threads performing an interruptible sleep
will leave the waiters flag on forcing the owner to do a wakeup even
when the waiter queue is empty.
That operation may lead to a deadlock in the case of doing a fake wakeup
on the "preferred" queue while the other queue has real waiters on it,
because nobody is going to wakeup the 2nd queue waiters and they will
sleep indefinitively.
A similar bug, is present, for lockmgr in the case the waiters are
sleeping with LK_SLEEPFAIL on.
Add a sleepqueue interface which does report the actual number of waiters
on a specified queue of a waitchannel and track if at least one sleepfail
waiter is present or not. In presence of this or empty "preferred" queue,
wakeup both waiters queues.

It looks like I didn't implement this when I imported MPSAFE TTY.
Applications like mail(1) still use this. I think it's conceptually bad.

The test for "same client" for the experimental nfs server over NFSv4
was broken w.r.t. byte range lock conflicts when it was the same client
and the request used the open_to_lock_owner4 case, since lckstp->ls_clp
was not set. This patch fixes it by using "clp" instead of "lckstp->ls_clp".
Fix three related problems in the experimental nfs client when
checking for conflicts w.r.t. byte range locks for NFSv4.
1 - Return 0 instead of EACCES when a conflict is found, for F_GETLK.
2 - Check for "same file" when checking for a conflict.
3 - Don't check for a conflict for the F_UNLCK case.
