other C files:
- Move sbcreatecontrol() and sbtoxsockbuf() to uipc_sockbuf.c. While
sbcreatecontrol() is really an mbuf allocation routine, it does its work
with awareness of the layout of socket buffer memory.
- Move pru_*() protocol switch stubs to uipc_socket.c where the non-stub
versions of several of these functions live. Likewise, move socket state
transition calls (soisconnecting(), etc) to uipc_socket.c. Moveo
sodupsockaddr() and sotoxsocket().
doesn't need to be first in softc now. (It was the whole
ifnet structure itself that needed to be first in the good
old days.) Fix the respective comment accordingly.
Add xrefs to ifnet(9) in some other comments while I'm here.

(The rest of needed changes were in my previous commit, which got
interrupted in the middle. Alas, CVS commits are not atomic.)

1) Eliminate an unnecessary check for fictitious pages. Specifically,
only device-backed objects contain fictitious pages and the object is
not device-backed.
2) Change the types of "psize" and "tmpidx" to vm_pindex_t in order to
prevent possible wrap around with extremely large maps and objects,
respectively. Observed by: tegge (last summer)

tests actually detect.
The bugs mostly canceled out, such that the worst possible failure
cases resulted in non-fatal over-allocations.

to the cloning framework and wait for "ifconfig create", h/w drivers
create interfaces for installed cards as soon as loaded. The issue
of devd(8) involuntarily reloading modules should be dealt with in a
different way.
temporary mapping created by locore so that the lowest two to four

In particular, bsdtar -x should not edit mode of existing dirs

FreeBSD/arm installworld install is only 170MB. The smallest SD card

Now that the IIC stuff has been sorted out, include that as well.
Include hints for the icee 16kb 16-bit i2c device. It should include
info about the temperature sensor as well, but that driver isn't quite
ready.
Add bpf for dhclient happiness.

some devices (and not others). To get instances onto the iicbus, one
now needs hints or an identify routine. We also do not probe the bus
for devices because many iic devices cannot be safely probed (and when
they can, the probe order turns out to be somewhat difficult to get
right).

a more complex aligned allocation algorithm, similar to that used for
alignment greater than the chunk size.

robustness of IIC transactions when parts aren't present. This also
removes a bunch of debug. This also moves this driver to 7-1
addressing rather than 6-0 addressing, which is more inline with all
the other iic drivers in the tree. I've tested this for about a
million years on the systems at work.
The relevant changes for FreeBSD (excerpt from the release note):
* Newly implemented CORE EXT words: CASE, OF, ENDOF, and ENDCASE. Also
added FALLTHROUGH, which works like ENDOF but jumps to the instruction
just after the next OF.
* Bugfix: John-Hopkins locals syntax now accepts | and -- in the comment
(between the first -- and the }.)
* Bugfix: Changed vmGetWord0() to make Purify happier. The resulting
code is no slower, no larger, and slightly more robust.
o tcp_input() now handles TCP segment sanity checks and preparations
including the INPCB lookup and syncache.
o tcp_do_segment() handles all data and ACK processing and is IPv4/v6
agnostic.
Change all KASSERT() messages to ("%s: ", __func__).
The changes in this commit are primarily of mechanical nature and no
functional changes besides the function split are made.
