This allows undocumented and problematic hardware on some systems
to be ignored, for instance, the USB keyboard/mouse that shows up
on a 12" albook that doesn't exist nor do anything other than eat up
the syscons keyboard. Another one is the unused USB cell in the old
366MHz iBook that locks up the machine when probed.
In a way this is temporary, since there are better fixes for the
above problems, but will be useful in the meantime by allowing
a keyboard to be used to help debug said fixes :)

I'm not sure why a credential was added to these in the first place, it is
not used anywhere and it doesn't make much sense:
The credentials for syncing a file (ability to write to the
file) should be checked at the system call level.
Credentials for syncing one or more filesystems ("none")
should be checked at the system call level as well.
If the filesystem implementation needs a particular credential
to carry out the syncing it would logically have to the
cached mount credential, or a credential cached along with
any delayed write data.

read the ethernet address from the attribute space hasn't been
implemented. Also add flags for the MBH10302. The flags and maddr
fields will be used when reading from the attribute space...
recursion from the VM is handled (and the calling code that allocates
buckets knows how to deal with it), we do not want to prevent allocation
from the slab header zones (slabzone and slabrefzone) if uk_recurse is
not zero for them. The reason is that it could lead to NULL being
returned for the slab header allocations even in the M_WAITOK
case, and the caller can't handle that (this is also explained in a
comment with this commit).
The problem analysis is documented in our mailing lists:
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=153445+0+archive/2004/freebsd-current/20041231.freebsd-current
(see entire thread for proper context).

This is just a workaround for a know problem with Motorola E1000
phone. Something is wrong with the configuration of L2CAP/RFCOMM
channel. Even though we set L2CAP MTU to 132 bytes (default RFCOMM
MTU 127 + 5 bytes RFCOMM frame header) and the phone accepts it,
the phone still sends oversized L2CAP packets. It appears that the
phone wants to use bigger (667 bytes) RFCOMM frames, but it does
not segment them according to the configured L2CAP MTU. The 667
bytes RFCOMM frame size corresponds to the default L2CAP MTU of
672 bytes (667 + 5 bytes RFCOMM frame header).
This problem only appears if connection was initiated from the
phone. I'm not sure who is at fault here, so for now just put
workaround in place. Quick look at the spec did not reveal any
anwser.

o Implement a shiny new algorithm to keep track of finger movement at
slow speeds. This dramatically reduces the level of questionable
language from users trying to resize windows.
o Properly catch the many extra buttons and dials which manufacturers
are known to screw onto Synaptics touchpad controllers. Currently,
up to seven buttons are known to work, more should work too.
o Add a number of sysctls allowing one to tune the driver to taste in
a simple way:
# Should the extra buttons act as axes or as middle button
hw.psm.synaptics.directional_scrolls
# These control the 'stickiness' at low speeds
hw.psm.synaptics.low_speed_threshold

As reported by Sean Shapira. This appears to be working. Eagle used
Fujitsu's vendor number, with a product number of 4 (which is the same
as the vendor number, which is a little suspect). Since there's no
apparent conflict, go ahead and use it.

vendor number and a product code of 4, which seems a little odd.
Still, there's no conflicts...
1/ doesn't matter on most of our architectures
2/ will never happen unless we start queueing multiple trasactions
to a single endpoint at one time (which we do not allow yet).
If anyone has a big_endian machine with EHCI they might check this
if they are having problems with EHCI but it's unlikely even there..

Now drivers that are MI can try resources that the driver knows may
be used by the device.
structures in IPX/SPX -- primarily, sequence numbering, PCB lists,
and PCBs for IPX raw sockets, IPX datagram sockets, and IPX/SPX.
As such, remove remove NET_NEEDS_GIANT() for IPX, and remove the
assertion of Giant in the ipxintr() IPX input path.
Note that IPX/SPX is not fully MPSAFE, and that there are some
problems with IPX/SPX locking that will require some further work.
However, it is now safe enough to run in general without the Giant
lock.

portion of IPX/SPX:
- Protect IPX PCB lists with the IPX PCB list mutex, in particular
when calling PCB and PCB list manipulation routines in ipx_pcb.c.
- Protect both IPX PCB state and SPX PCB state using the IPX PCB
mutex.
- Generally annotate locking, as well as adding liberal use of lock
assertions to document locking requirements.
- Where possible, use unlocked reads when reading integer or smaller
sized socket options on SPX sockets.
- De-spl throughout.
Notes:
- spx_input() expects both the list mutex and PCB mutex to be held
on entry, but will release both on return. Because sonewconn() is
called from spx_input(), it may actually drop one PCB lock and
acquire another during generation of a new connection, meaning the
caller is not in a position to unlock the PCB mutex.

- spx_close(), spx_disconnect(), spx_drop(), and spx_usrclosed() all
always free's the spxpcb invalidating the argument, so a return
value is not required to indicate if it has.
- Annotate that the cb arguments to each of these functions is
invalidated via a comment.
- When tearing down a pcb due to sonewconn() having failed, mark the
cb as NULL; later, when deciding whether to store trace information
due to SO_DEBUG, check that cb is not NULL before dereferencing or
a NULL pointer dereference may occur.
