PCPU_PTR() curthread can migrate on another CPU and get incorrect
results.
- Fix a similar race into witness_warn().
- Fix the interlock's checks bypassing by correctly using the appropriate
children even when the lock_list chunk to be explored is not the first
one.
- Allow witness_warn() to work with spinlocks too.

the Sierra and Novatel devices, ignore all umass devices and hide the umass
devices that represent the CD ROM devices (but not the SD card slot in the
Huawei Mobile dongle).
Note: This driver in FBSD7 seems to suffer from memory corruption when used
with an Option GT Quad. The E220 however works flawlessly.
Also add the ID for the Option GTMaxHSUPA, provided by Olivier Fromme.
Read the other way round this means that even with the checks
the m_len turned negative in some cases which led to panics.
The reason to my understanding seems to be that the checks are wrong
(also for v4) ignoring possible padding when checking cmsg_len or
padding after data when adjusting the mbuf.
Doing proper cheks seems to break applications like named so
further investigation and regression tests are needed.

- Change the ddb(4) commands to be more useful (by thompsa@):
- `show ttys' is now called `show all ttys'. This command will now
also display the address where the TTY data structure resides.
- Add `show tty <addr>', which dumps the TTY in a readable form.
- Place an upper bound on the TTY buffer sizes. Some drivers do not want
to care about baud rates. Protect these drivers by preventing the TTY
buffers from getting enormous. Right now we'll just clamp it to 64K,
which is pretty high, taking into account that these buffers are only
used by the built-in discipline.
- Only call ttydev_leave() when needed. Back in April/May the TTY
reference counting mechanism was a little different, which required us
to call ttydev_leave() each time we finished a cdev operation.
Nowadays we only need to call ttydev_leave() when we really mark it as
being closed.
- Improve return codes of read() and write() on TTY device nodes.
- Make sure we really wake up all blocked threads when the driver calls
tty_rel_gone(). There were some possible code paths where we didn't
properly wake up any readers/writers.
- Add extra assertions to prevent sleeping on a TTY that has been
abandoned by the driver.
- Use ttydev_cdevsw as a more reliable method to figure out whether a
device node is a real TTY device node.

the user selected and then recursively installing their dependencies, finally
installing the ones the user selected after the recursion unwinds. Since
users often select "high-level" packages that are on a higher numbered
disc for the multi-volume release CDROMS this resulted in excessive disc
swapping while installing things like kde, gnome, etc.
Cut down on disc swapping by iterating through the disc volumes one at a
time if we notice the package set is on multiple volumes. If a package
is on a higher volume don't install it yet, but still "process it" so we
get its dependencies installed. Because of the way the package sets for
releases get assembled we're guaranteed dependencies will be on the same
volume or lower.

this eliminates some problems of locking, e.g, a thread lock is needed
but can not be used at that time. Only the process lock is needed now
for new field.

The following sysctls were removed:
hw.psm.synaptics.low_speed_threshold
hw.psm.synaptics.min_movement
hw.psm.synaptics.squelch_level
An overview of this new driver and a short documentation about the added
sysctls is available on the wiki:

possible others on new hardware.
On G5 systems, there are several otherwise standard PCI devices
(Serverworks SATA) that will not allow their interrupt properties to be
written, so this information must be supplied directly from Open Firmware.

This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).
Only netbooting is supported at the moment.

This supports 1Gbps Ethernet engine found on ARM-based SOCs (Orion, Kirkwood,
Discovery), as well as on system controllers for PowerPC processors (MV64430,
MV6446x).
The following advanced features are supported:
- multicast
- VLAN tagging
- IP/TCP/UDP checksum calculation offloading
- polling
- interrupt coalescing

- Syria goes to DST at 1 November instead of 1 October.
- Niue is now located at the right side of the equator.
freaks me out. But it turns out we might be able to generalize
a few of the other things RE uses to assemble the package trees
for releases if the DVDs use a naming theme close to what is used
for the CDROMS (disc1, disc2, etc). So change the name to dvd1.
Hopefully this way src/release/scripts/{package-split.py,package-trees.sh}
can be generalized instead of copied-and-hacked.

the last byte of the ethernet address was not read which in turn
resulted in getting 5 out of the 6 bytes of ethernet address and
always returned ENOENT. I did not notice the bug on FPGA version
because of additional configuration data in EEPROM.

example the Huawei Mobile has an SD card slot on the second interface.
- Do not attach to Qualcomm and Novatel cards. If ignored these cards will
switch to modem mode automatically it seems.
- Reduce the priority on generic attachment to the appropriate level.
Note: A better solution is to send an eject command straightaway, but that can
be left till later.

Also, a minor tweak to load/store pointers. Other changes from NetBSD

The above families of SOCs are built around CPU cores compliant with ARMv5TE
instruction set architecture definition. They share a number of integrated
peripherals. This commit brings support for the following basic elements:
* GPIO
* Interrupt controller
* L1, L2 cache
* Timers, watchdog, RTC
* TWSI (I2C)
* UART
Other peripherals drivers will be introduced separately.
