190320e237 Add a missing priv check in key_attach to prevent non-su users
from messing with the spdb and sadb.

Problem sneaked in with the fast_ipsec+v6->ipsec merger by no
longer going via raw_usrreqs.pr_attach.

dbac8ff400 Move the agp(4) driver from sys/pci to sys/dev/agp. __FreeBSD_version was
bumped to 800004 to note the change though userland apps should not be
affected since they use <sys/agpio.h> rather than the headers in
sys/dev/agp.

b0db4c9328 Add private tx/rx buffer management to support large frame sizes
and update the rx code to handle multiple frames in a single usb
transfer.  AX772 parts (at least) exhibit many input errors when
operated with a 2K rx buffer and no errors w/ a 4K rx buffer (it's
unclear what the cause of the errors is for 2K so this may just be
covering up the real issue).  Larger rx buffer sizes show no
significant performance improvement for AX772.  Bypassing the common
buffer management routines also eliminates an extra context switch
on every packet which noticeably improves performance (TCP netperf
rx goes from 45 Mb/s to 85 MB/s).

8b18769048 Limit total playback channels to just 1, for ALi M5451.
The reliability of it's multi DAC / playback channels is
not that good. Enabling vchans make the bug more visible
since playback allocation will look for possible free
hardware channels first (i.e: the next DAC, the very first
has been consumed by vchan mixer) which in this case has
been proven faulty.

db27a9dac7 Make it easier to add more ptys to the pty(4) driver:
- Use unit2minor() and minor2unit() to generate minor numbers to support
  unit numbers higher than 255.
- Use simple string operations on the 'names' array rather than hard-coded
  constants and switch statements so that more ptys can be added by simply
  expanding the 'names' array.

a03be42da6 Put back devstat support that was lost during GEOM transition. Initially,
I've tried to move md(4) to use geom_disk class, like real disks do, but
this requires major rework of some of the existing features such as
configuration dumping for example. Therefore just putting devstat support
directly into md(4) seems to be optimal solution.

Now you can see md(4) stats in `systat -vm' again.

32a8088fef Driver for the Apple System Management Console (SMC). This hardware is
present on the MacBook, MacBook Pro, and Intel MacMini.

This driver exports information via sysctl in its private sysctl tree
dev.asmc.*. You can get information about temperatures, fan speeds, the
keyboard light sensor and the Sudden Motion Sensor (SMS).
The SMS is very useful to park the disk heads when the laptop is
moved. Basically, the SMS is setup so that, under movement, we get an
interrupt on irq 6 and a devd notification is sent.

897c0f57d4 1) dummynet_io() declaration has changed.
2) Alter packet flow inside dummynet: allow certain packets to bypass
dummynet scheduler. Benefits are:

- lower latency: if packet flow does not exceed pipe bandwidth, packets
  will not be (up to tick) delayed (due to dummynet's scheduler granularity).
- lower overhead: if packet avoids dummynet scheduler it shouldn't reenter ip
  stack later. Such packets can be fastforwarded.
- recursion (which can lead to kernel stack exhaution) eliminated. This fix
  long existed panic, which can be triggered this way:
  	kldload dummynet
	sysctl net.inet.ip.fw.one_pass=0
	ipfw pipe 1 config bw 0
	for i in `jot 30`; do ipfw add 1 pipe 1 icmp from any to any; done
	ping -c 1 localhost

3) Three new sysctl nodes are added:
net.inet.ip.dummynet.io_pkt -		packets passed to dummynet
net.inet.ip.dummynet.io_pkt_fast - 	packets avoided dummynet scheduler
net.inet.ip.dummynet.io_pkt_drop -	packets dropped by dummynet

P.S. Above comments are true only for layer 3 packets. Layer 2 packet flow
     is not changed yet.

o do not override the home channel recorded for the sta when the frame is
  received off-channel; this fixes a problem where we might think the sta
  was operating on the channel the frame was received on causing association

o don't include rssi of off-channel frames in the avg rssi used to select

89b57fcf01 Fix for the panic("vm_thread_new: kstack allocation failed") and
silent NULL pointer dereference in the i386 and sparc64 pmap_pinit()
when the kmem_alloc_nofault() failed to allocate address space. Both
functions now return error instead of panicing or dereferencing NULL.

As consequence, vmspace_exec() and vmspace_unshare() returns the errno
int. struct vmspace arg was added to vm_forkproc() to avoid dealing
with failed allocation when most of the fork1() job is already done.

The kernel stack for the thread is now set up in the thread_alloc(),
that itself may return NULL. Also, allocation of the first process
thread is performed in the fork1() to properly deal with stack
allocation failure. proc_linkup() is separated into proc_linkup()
called from fork1(), and proc_linkup0(), that is used to set up the
kernel process (was known as swapper).
