There were two bugs:
* If the initial lowest rate didn't go through the loop at least once,
the AMRR rate index would be the highest rate in the table
(eg the rix mapping to MCS15) but rate would stay at the default
value, namely 0.
This meant that the initial rate selection would be MCS15 _but_ the
node ni_txrate value would be MCS0.
* If the node is 11n, then break out of the loop correctly. Beforehand,
my initial 11n AMRR commit would immediately exit out as it would
fail the 11n check, then it would always fall through to the non-11n
rate which would then see if it was < 36mbit (ie, "72"), which would
always match. Hence, it'd always return MCS15.
Tested:
* Intel Centrino 2230 STA (local changes), STA mode
* Intel Wifi 5100, STA
This is a no-op for now!
* Add a new flag value for "there are no extra bits" for some random
field;
* Add a definition for the maximum number of calibration entries in
the calibration data cache in iwn_softc. It's not yet used.
* Add regulatory bands for the 2030 NIC.

Pointy hats to: cperciva & everybody who didn't proofread EN-13:04 enough
to ILP32. Otherwise dtrace -G will attempt to use it on amd64 if it can't
determine which data model to use, which happens when -64 is omitted and
no object files are provided, e.g. with
# dtrace -G -n BEGIN
This would result in a linker error, but now works properly.
Also remove an unnecessary #ifdef.

NB: The "halt" signal seems to be used on XenServer only. The OSS

the kernel itself: If building for the same architecture as the build host,
the kernel build assumes that the host toolchain is capable of building the
kernel. If it's not, "make kernel-toolchain" will bootstrap a new set of
tools that will work.
With this change the same assumptions are made for building kernel tools,
and the existing host toolchain is used to do the build (notably, the build
doesn't link the tools with the legacy libraries, which may not even exist).
If ever for some reason the host toolchain isn't capable of building the
kernel tools, then doing a "make kernel-toolchain" will bootstrap newer
tools to get the job done.
So when built as part of buildworld or kernel-toolchain, the kernel tools
are built using the XMAKE (via BMAKE) commands and environment. When built
as part of building just the kernel on a same-target host, the tools are
built using the new KTMAKE commands and environment. What doesn't jump
out at you in the diffs is that the difference between BMAKE and KTMAKE
is that BMAKE contains this magic line which changes how the build is done
because it changes what files get included for .include <bsd.prog.mk> and
other standard includes:
MAKEFLAGS="-m ${.CURDIR}/tools/build/mk ${.MAKEFLAGS}"
and KTMAKE doesn't, and contains this instead:
TOOLS_PREFIX=${WORLDTMP}
Hopefully this brings the "how to build aicasm with the right toolchain"
saga to a conclusion that works in all usage scenarios that have
historically been supported.
The release.sh (based heavily on generate-release.sh) has been
used for the 9.2-RELEASE and 10.0-RELEASE cycles, so make sure
there is no confusion on what is currently being used by having
two similar scripts.
A big "thank you" to Nathan Whitehorn, the author of the
generate-release.sh script, for writing this utility.

words, every architecture is now auto-sizing the kmem arena. This revision
changes kmeminit() so that the definition of VM_KMEM_SIZE_SCALE becomes
mandatory and the definition of VM_KMEM_SIZE becomes optional.
Replace or eliminate all existing definitions of VM_KMEM_SIZE. With
auto-sizing enabled, VM_KMEM_SIZE effectively became an alternate spelling
for VM_KMEM_SIZE_MIN on most architectures. Use VM_KMEM_SIZE_MIN for
clarity.
Change kmeminit() so that the effect of defining VM_KMEM_SIZE is similar to
that of setting the tunable vm.kmem_size. Whereas the macros
VM_KMEM_SIZE_{MAX,MIN,SCALE} have had the same effect as the tunables
vm.kmem_size_{max,min,scale}, the effects of VM_KMEM_SIZE and vm.kmem_size
have been distinct. In particular, whereas VM_KMEM_SIZE was overridden by
VM_KMEM_SIZE_{MAX,MIN,SCALE} and vm.kmem_size_{max,min,scale}, vm.kmem_size
was not. Remedy this inconsistency. Now, VM_KMEM_SIZE can be used to set
the size of the kmem arena at compile-time without that value being
overridden by auto-sizing.
Update the nearby comments to reflect the kmem submap being replaced by the
kmem arena. Stop duplicating the auto-sizing formula in every machine-
dependent vmparam.h and place it in kmeminit() where auto-sizing takes
place.

Move the installation of /usr/tests/lib/Kyuafile from src/tests/lib/
to src/lib/. This is to keep the src/tests/ hierarchy unaware of the
rest of the tree, which makes things clearer in general. In particular:
1) Everything related to the construction of /usr/tests/lib/ is kept
in src/lib/. There is no need to think about different directories
and how they relate to each other. (The same applies for libexec,
usr.bin, etc. but these are not yet handled.)
2) src/tests becomes the place to keep cross-functional test programs
and nothing else, which also helps in simplifying things.

There is no reason to keep the two knobs separate: if tests are

The addition of the TESTS knob and its enabling of the build of tests in
lib/libcrypt/tests/ broke the build. The reason is that we cannot descend
into tests/ subdirectories until all prerequisites have been built, which
in the case of tests may be "a lot of things" (libatf-c in this case).
Ensure that we do not walk tests/ directories during the bootstrapping of
the libraries as part of buildworld.
