tree since 2003/02/20, and I recently cleaned it up. I'd even closed
the PR that I obtained this from Fri Jul 18 23:25:08 MDT 2003 since
I looked at my p4 tree.

altq(4) (+MFC), ongoing locking work in the network stack, TCP RST
bugfix (+MFC), SACK bugfixes (+MFC), RFC 1644 T/TCP support removed,
gpt(8) create -f (+MFC), NO_NIS (+MFC), ncal(1) -m (+MFC).
These items mostly come from commit logs for November 2004.
occurred with large read-ahead requests. This only affected
formats that incorrectly make large requests (ZIP did this until
recently) or with block sizes over 32k.
memory disk is larger than the number of available sf_bufs, this improves
performance on SMPs by eliminating interprocessor TLB shootdowns. For
example, with 6656 sf_bufs, the default on my test machine, and a 256MB
swap-backed memory disk, I see the command
"dd if=/dev/md0 of=/dev/null bs=64k" achieve ~489MB/sec with the default,
shared mappings, and ~587MB/sec with CPU private mappings.
base transfer speed to CAM. The actual value used (40MB/s) is fairly
arbitrary, but assumes the same 33% overhead as was implied by the
1MB/s figure we used for USB1 devices.
are not added to the list(s) of available settings. However, other drivers
can call the CPUFREQ_DRV_SETTINGS() method on those devices directly to
get info about available settings.
Update the acpi_perf(4) driver to use this flag in the presence of
"functional fixed hardware." Thus, future drivers like Powernow can
query acpi_perf for platform info but perform frequency transitions
themselves.
on dev.cpu.0 will affect all of the CPUs together. In the future,
independent control will be supported but this is good enough for now.
Check that the timecounter isn't TSC before switching (from Colin Percival.)
former is callable from user space and the latter from the kernel one. Make
kernel version take additional argument which tells if the respective call
should check for additional restrictions for sending signals to suid/sugid
applications or not.
Make all emulation layers using non-checked version, since signal numbers in
emulation layers can have different meaning that in native mode and such
protection can cause misbehaviour.
As a result remove LIBTHR from the signals allowed to be delivered to a
suid/sugid application.
