code in ipl.s and icu_ipl.s that used them was removed when the
interrupt thread system was committed. Debuggers also knew about
Xresume* because these labels hide the real names of the interrupt
handlers (Xintr*), and debuggers need to special-case interrupt
handlers to get the interrupt frame.
Both gdb and ddb will now use the Xintr* and Xfastintr* symbols to
detect interrupt frames. Fast interrupt frames were never identified
correctly before, so this fixes the problem of the running stack
frame getting lost in a ddb or gdb trace generated from a fast
interrupt - e.g. when debugging a simple infinite loop in the kernel
using a serial console, the frame containing the loop would never
appear in a gdb or ddb trace.

1. To cross-build, one now needs to set TARGET_ARCH, and not the
MACHINE_ARCH. MACHINE_ARCH should never be changed manually!
2. Initialize DESTDIR= explicitly for bootstrap-tools, build-tools,
and cross-tools stages. This fixes broken header and library
dependencies problem. We build them in the host environment,
and obviously want them to depend on host headers and libraries.
The problem with broken header dependencies for bootstrap-tools
and cross-tools was already partially solved (see BOOTSTRAPPING
tests in bsd.prog.mk and bsd.lib.mk), but it was still there for
build-tools if the user ran "make world DESTDIR=/foo". Also,
for all of these stages, the library dependencies were broken
because of how bsd.libnames.mk define DPADD members.
We still provide a glue to install bootstrap- and cross-tools
under the ${WORLDTMP}.
Removed PATH overrides for bootstrap-, build-, and cross-tools
stages. There is just no reason why we would need to override
it, and the hacks to clean up the ${WORLDTMP} in the -DNOCLEAN
case are no longer needed with fixes from this step.
That is, we now never use ${WORLDTMP} headers and libraries,
and we don't use any ${WORLDTMP} installed binaries during
these stages. Again, these stages depend solely on the host
environment, including compiler, headers, and libraries.
3. Moved "miniperl" back from cross-tools (it has nothing to do
with a cross-compiler) to build-tools where it belongs. The
change from step 1 let to do this. Also, to make this work,
build-tools targets of "cc_tools" and "miniperl" were modified
to call "depend". Here follow the detailed explanations.
There are two categories of build tools, for now. In the first
category there are "cc_tools" and "miniperl". They occupy the
whole (sub)directory, and nothing needs to be done in this
subdirectory later during the "all" stage. They are also
constructed using system makefiles. We must build the .depend
early in the build-tools stage because:
1) They use (and depend on) the host environment.
2) If we don't do this in build-tools, the "depend" stage of
buildworld will do this for us; wrong library and header
dependencies will be recorded (DESTDIR=${WORLDTMP}) and,
what's worse, the "all" stage may then clobber the
build-architecture format tools (that we built in the
build-tools stage) with the target-architecture format
ones, breaking cross build.
In the second category there are all other build-tools. They
share their directory with the "main" module that needs them
in the "all" stage, and they don't show up themselves in the
.depend file. The portion of this fix was already committed
in gnu/usr.bin/cc/cc_tools/Makefile,v 1.52.
4. "libperl" is no longer a build tool, and "miniperl" is the
stand-alone application. I had to make this change because
build-tools and "all" stages share the same object directory.
Without this change, if we cross compile, libperl.a is first
built for the build architecture during the build-tools stage
(for the purposes of immediate linkage with "miniperl").
Later on, the "all" stage sees this library as up-to-date,
and doesn't rebuild it. The effect is that the wrong format
static libperl library is installed with installworld.
5. Fixed "includes" to install secure/lib/libtelnet headers if
required.

"build-tools". If we do not do this, the "depend" stage of
"buildworld" will build ``.depend'' and it will record the wrong
library and header dependencies (DESTDIR=${WORLDTMP}). Even worse,
the "all" stage may clobber build-architecture-format build tools
built in the "build-tools" stage with target-architecture-format ones.

bug in lib/libc/gen/basename.c rev 1.1. There is no way for us to test
what revision of basename() we have in libc, thus this change.

misuse of /usr/src/include headers. This REALLY fixes
the 20010919 src/UPDATING entry.
With this patch the 4.2-RELEASE box was able to survive
the 5.0-CURRENT "make world".
Beat over the head with this patch: obrien
The version of the kernel has no bearing on what is in libc.
We now search for basename in libc to determin if we need to include
the libiberty version in the build.
This is all still a bit bogus as it will (like the sysctl method) cause
basename.o to be linked into the cross-build as well as the host build. It
would probably be better to test if we were doing the initial host build and
unconditionally include that. Once we've generated the target libc we know
that basename is available. (maybe test for $TOOLS_PREFIX or something).

make the kernel aware that there are smaller units of scheduling than the

This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.
