First of all, current behavior is not documented and confusing,
and it can be very dangerous in the following sequence:
find -L . -type l
find -L . -type l -delete
(the second line is even suggested by find(1)).
Instead simply refuse to proceed when -L and -delete are both used.
A descriptive error message is provided.
The following command can be safely used to remove broken links:
find -L . -type l -print0 | xargs rm -0
To do: update find(1)

shared uses of a resource are recorded on a sub-list hanging off
a main resource object on a main resource list;
without this change a shared resource (e.g. irq) is reported only
once by devinfo -r/-u;
with this change the resource is reported for each driver that
allocates it (which is even more than what vmstat -i -a reports).

net.inet.ip.fw.one_pass is a classic ip_input.c variable and is used in
the pfil and bridge code as well. As ipfw is loadable we need to always
provide it. That is the reason why it lives in struct vnet_inet and
not in struct vnet_ipfw.

possible future I-cache coherency operation can succeed. On ARM
for example the L1 cache can be (is) virtually mapped, which
means that any I/O that uses temporary mappings will not see the
I-cache made coherent. On ia64 a similar behaviour has been
observed. By flushing the D-cache, execution of binaries backed
by md(4) and/or NFS work reliably.
For Book-E (powerpc), execution over NFS exhibits SIGILL once in
a while as well, though cpu_flush_dcache() hasn't been implemented
yet.
Doing an explicit D-cache flush as part of the non-DMA based I/O
read operation eliminates the need to do it as part of the
I-cache coherency operation itself and as such avoids pessimizing
the DMA-based I/O read operations for which D-cache are already
flushed/invalidated. It also allows future optimizations whereby
the bcopy() followed by the D-cache flush can be integrated in a
single operation, which could be implemented using on-chips DMA
engines, by-passing the D-cache altogether.
register 0x52, not ctrl1. This appears to be a mistake in the bcm
reverse engineering page, and has been corrected there. Tracing
through the code, this is more in keeping with the "documented"
register. Sephe thinks it looks interesting and may be worth
fixing. :)

These sysctls don't need any form of locking. At least cp_times is used
by powerd very often, which means I get 50% less calls to non-MPSAFE
sysctls on my system. The other 50% is consumed by dev.cpu.0.freq, but
this seems to need Giant for Newbus.
-- A routing socket message is not generated when an IPv6 address is
either inserted or deleted from an interface. The missing routing
message problem was discovered by Randall Stewart and Michael Tuxen
during SCTP testing.
-- Previously when an IPv6 address is configured on an interface, if the
prefix length is /128, then a host route is instaleld in the kernel
for this address. But this host route is not deleted when that IPv6
address is removed from the interface.

believe it was a BCM4319. However, it is the a/b/g variation of the
BCM4318. The chip itself is labelled BCM4318EKFBG, and the board is
BCM94318MKABG.
Paradox's patch includes the type of 802.11 wireless for each card,
but changes all the names (I don't think the latter is quite right).
Import that part of the patch, but keep the current set of BCM names
(with a minor tweak for the 4306 ones). I'll need to verify them via
some other means.
