btuartd(8) should be named btattach(8) for consistency
with other parts of NetBSD
make btattach(8) a single-use tool for less complexity
device specicific initialisation (from btuart(4)) is carried
out prior to activating the line discipline (in btattach(8)),
which simplifies the API somewhat and means that the user
tool and the kernel do not need to be kept in sync.
btuart(4) driver is much reduced; naming is made consistent
and all tsleep() and delay() are removed to userland
"retro" computers, but NetBSD also runs a growing number of rare
and retro add-on cards. With this patch, NetBSD supports the IDEC
Supervision/16, a black&white image capture board for the 16-bit
ISA bus. Approximate date of manufacture: 1991. Total instances
known to be in use throughout the world: one.
Coming soon; isvctl(8), the utility program for capturing 8-bit,
512x480 images at speeds of up to 6 frames per second.

While it's true that it's part of the traditional 4.4BSD security model,
there may come a time where a different "primary" security model used for
fine-grained privileges (ie., splitting root's responsibilities to various
privileges that can be assigned) may want to still have a securelevel
setting.
Idea from Daniel Carosone:
http://mail-index.netbsd.org/tech-security/2006/08/25/0001.html
The location of the removed files, for reference, was:
src/secmodel/bsd44/secmodel_bsd44_securelevel.c
src/secmodel/bsd44/securelevel.h
This file simplifies the build of test programs, either written in C++
or in sh. It hides the internals of atf, e.g. by silently linking
against -latf or calling atf-compile.
It also takes care of installing an Atffile for each new test directory.
This adds reachover Makefiles to build and install the atf tools.
Some are public, thus installed in /usr/bin, and others are internal
and therefore installed in /usr/libexec.
This adds reachover Makefiles to build the libatf library and enables it in
the parent Makefile.
Things to review in this change:
* Add proper version numbers in the shlib_version files.
* Is libatf properly listed in lib/Makefile? It theoretically needs
libstdc++, but the resulting binary library is not linked against it.

- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.
- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.
- Replace the hand-made reader/writer lock with a krwlock.
- Keep `vn_cow_*' functions and mark as obsolete.
- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.

instead of adding/subtracting our own IPv4 header.
There are many benefits: gre(4) needn't grok the outer encapsulation
header any longer, so this simplifies the gre(4) code. The IP
stack needn't grok GRE, so it is simplified, too. gre(4) will
benefit from optimizations in the socket code. Eventually, gre(4)
will gain an IPv6 encapsulation with very few new lines of code.
There is a small performance loss. A 133 MHz, 486-class AMD Elan
sinks/sources a TCP stream over GRE with about 93% the throughput
of the old code. TCP throughput on a 266 MHz, 586-class AMD Geode
is about 96% the throughput of the old code. A 175-MHz ADM5120
(MIPS) only sinks a TCP stream over GRE at about 90% of the old
code; I am still investigating that.
I produced stripped-down versions of sosend() and soreceive() for
gre(4) to use. They are guaranteed not to block, so they can be
called from a software interrupt and from a socket upcall,
respectively.
A kernel thread is no longer necessary for socket transmit/receive,
but I didn't get around to removing it, yet.
Thanks to Matt Thomas for suggesting the use of stripped-down socket
code and software interrupts, and to Andrew Doran for advice and
answers concerning software interrupts, threads, and performance.
Can be used by applications that have their own SIGINT (et al)
handlers and want to exit in a manner that correctly
signals to the parent that the process was terminated by a signal.

Most complex function implementations are from the "c9x-complex" library,
originating from the "cephes" math library, see
http://www.netlib.org/cephes/, from Stephen L. Moshier, incorporated and
redistributed with the NetBSD license by permission of the author.
Error behaviour and other boundary conditions (branch cuts)
need to be looked at.
For namespace sanity, I've done the rename/weak alias procedure to
most of the exported functions which are also used internally.
Didn't do so for sin/cos(f) yet because assembler implementations use
them directly, and renaming functions shared between the main libm
and the machine specific "overlay" might raise binary compatibility
issues.

Add a new libc function, getpeereid() to easily get at the euid and egid.
