o recognize ixp435 cpu
o change memory layout for for ixp4xx to not assume memory is aliases
to 0x10000000 (Cambria/ixp435 memory starts at zero)
o handle 64 irqs for ixp435
o dual EHCI USB 2.0 controller integral to ixp435
o overhaul NPE code for ixp435 and better MAC+MII naming
o updated NPE firmware (including NPE-A image for ixp435/ixp465)
o Gateworks Cambria board support:
- IDE compact flash
- MCU
- front panel LED on i2c bus
- Octal LED latch
Sanity-tested with NFS-root on Avila and Cambria boards. Requires
pending boot2 mods for CF-boot on Cambria.

error is not EAGAIN. Several sysctls that inspect another process use
p_candebug() for checking access right for the curproc. p_candebug()
returns EAGAIN for some reasons, in particular, for the process doing
exec() now. If execing process tries to lock Giant, we get a livelock,
because sysctl handlers are covered by Giant, and often do not sleep.
Break the livelock by dropping Giant and allowing other threads to
execute in the EAGAIN loop.
Also, do not return EAGAIN from p_candebug() when process is executing,
use more appropriate EBUSY error [1].

state changes. This change modifies tunopen and tunclose to call the
if_link_state_change() function. Among other things, this will result in
devd(8) receiving events from devctl(4) for linkup/link down. This allows
us to do several useful things, including initializing tunnel parameters
and adding routes.

on a best-effort basis. Teach vn_fullpath to use this new VOP if a
regular VFS cache lookup fails. This VOP is designed to supplement the
VFS cache to provide a better chance that a vnode-to-name lookup will
succeed.
Currently, an implementation for devfs is being committed. The default
implementation is to return ENOENT.
A big thanks to kib for the mentorship on this, and to pho for running it
through his stress test suite.

One thing I didn't expect many applications to use, was kqueue() on
pseudo-terminal master devices. There are applications that use kqueue()
on the TTY itself (rtorrent, etc). That doesn't mean we shouldn't
implement this. Libraries like libevent use kqueue() by default, which
means they wouldn't be able to use kqueue().
The old TTY layer implements a very broken version of kqueue() by
performing the actual polling on the TTY device.

When I added RLIMIT_NPTS, I forgot to add it to rlimit_ident[]. Make
sure the rlimit_ident[] array is always RLIM_NLIMITS elements big. So if
we ever forget to add new rlimits to this list again. it will contain a
null pointer, instead of random data.

missed under VIMAGE_GLOBAL.
Start putting the extern declarations of the virtualized globals
under VIMAGE_GLOBAL as the globals themsevles are already.
This will help by the time when we are going to remove the globals
entirely.
While there garbage collect a few dead externs from ip6_var.h.

o Try to be smarter about reading the ExCA CSC register. Now, we only
do it for 16-bit cards. Add some experimental code to treat it like
a power interrupt, but I'm not 100% sure that I like it. It may be
removed upon further testing. It seemed to help in one test case, but
the evidence may be inconclusive. This may be beneficial for cleaning up
exca_reset and exca_wait_ready.
o Check for CSTS events on the socket event register. We ask for it when
we're powering up a card, but I don't think we're otherwise using
it. Just ACK the interrupt for now. In theory, we can use it
instead of the busy wait we do in cbb_cardbus_reset. More research
is necessary to see if we can optimize things there when we're
waiting for the DEVVENDOR register to become valid.
o Rework the comments a bit. Minor tidying up. Etc.
