Since this is called in fork() it does rather need to give the child
process the parent's emulation root.
This means that (for example) an emulated shell will, by default, run
programs from the emulation root.
avoid having to allocate space in the 'stackgap'
- which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
search for absolute pathnames in the emulation root, if that fails it will
retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
the real root is returned instead (matching the behaviour of emul_lookup,
but being a cheap comparison here) so that programs that scan "../.."
looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.
instead of rtcache_free(). It is not desirable to clear the cached
destination as well as the route, however, rtcache_free() will
eventually release all resources held by the cache, including the
destination.
Add some additional diagnostic assertions.

the Linux (BlueZ) API.
- L2CAP or RFCOMM connections can require the baseband radio link
mode be any of:
authenticated (devices are paired)
encrypted (implies authentication)
secured (encryption, plus generate new link key)
- for sockets, the mode is set using setsockopt(2) and the socket
connection will be aborted if the mode change fails.
- mode settings will be applied during connection establishment, and
for safety, we enter a wait state and will only proceed when the mode
settings are successfuly set.
- It is possible to change the mode on already open connections, but
not possible to guarantee that data already queued (from either end)
will not be delivered. (this is a feature, not a bug)
- bthidev(4) and rfcomm_sppd(1) support "auth", "encrypt" and
"secure" options
- btdevctl(8) by default enables "auth" for HIDs, and "encrypt" for
keyboards (which are required to support it)
+ Add pxartc and lcd(commented out) and pxaudc and pxamci (commented out).
lcd and pxamci not support yet.
+ Remove slhci.
+ Change name of expansion bords the console-{hw,st} from waysmall-{hw,st}.

vax. From OpenBSD:
Addressing mode work by Jim Uhl:
- fix PC relative byte displacement in getaddr_byte
- add support for word displacement to getaddr_byte
This allows certain libm inverse trig functions to work on systems
that lack a native polyd instruction.
Do not clear IFF_OACTIVE and reset the transmit watchdog timer
unless we have actually freed some transmit resources. This prevents
my wireless routers from needlessly entering ath_start() without
any transmit resources. If the MAC's transmitter has frozen, also,
then the driver will take the "out of xmit buffers" path in
ath_start(), which sets OACTIVE without activating the transmit
watchdog. That freezes the transmit path until the driver is reset.
XXX The "out of xmit buffers" path in ath_start() needs more
XXX attention.
