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).

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

Make it easier to add more ptys to the pty(4) driver:

constants and switch statements so that more ptys can be added by simply

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

directly into md(4) seems to be optimal solution.

Driver for the Apple System Management Console (SMC). This hardware is

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.

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.

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).

The intent of the freeing the (zeroed) page in vm_page_cache() for
default object rather than cache it was to have
vm_pager_has_page(object, pindex, ...) == FALSE to imply that there is
no cached page in object at pindex. This allows to avoid explicit
checks for cached pages in vm_object_backing_scan().
For now, we need the same bandaid for the swap object, otherwise both
the vm_page_lookup() and the pager can report that there is no page at
offset, while page is stored in the cache. Also, this fixes another
instance of the KASSERT("object type is incompatible") failure in the
