We ought to be consistent across our Tier-1 and nearly-Tier-1
architectures, so enable Capsicum for 32-bit armv6/armv7 by default.

- In configurations with a pseudo devices section, move 'device crypto'
into that section.
- Use a consistent comment. Note that other things common in kernel
configs such as GELI also require 'device crypto', not just IPSEC.

Missed in r337940.
(It's not like there are any crypto files IPsec doesn't pull in, so it is
unclear what not defining the crypto option was supposed to achieve.)

HEAD. Enable VIMAGE in GENERIC kernels and some others (where GENERIC does
not exist) on HEAD.
Disable building LINT-VIMAGE with VIMAGE being default.
This should give it a lot more exposure in the run-up to 12 to help
us evaluate whether to keep it on by default or not.
We are also hoping to get better performance testing.
The feature can be disabled using nooptions.

Transition all boards that support arm cortex CPUs to armv7. This
leaves two armv6 kernels in the tree. RPI-B, which uses the BCM2835
which has a ARM1176 core, and VERSATILEPB, which is a qemu board setup
around the time RPI-B went in. Copy std.armv6 to std.armv7, even
though that duplicates a lot of stuff. More work needs to be done to
sort out the duplication.

In real GNU libgcc, _Unwind_Backtrace is published with GCC_3.3 version
for all architectures but ARM. For ARM it's publishes with GCC_4.3.0
version.
This exception is not implement in your version of libggc, thus we
export _Unwind_Backtrace with bad version. To maintain backward
compatibility, publish _Unwind_Backtrace twice, once as compatible
symbol with GCC_3.3 version, and once as default symbol with
GCC_4.3.0 version.
While I'm in, fix typo in GCC_4.2.0 to GCC_4.3.0 inheritance declaration.

to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.
Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.
This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.
Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.

All armv6 processors are plenty fast enough for HZ=1000.
No changes are made for older arm systems, because some chips are a bit
wimpy for 1000 while others do fine, so it has to be set on a per-config

that applies to the entire arch.
Add the ARM_NEW_PMAP option to std.armv6. This is working well in early
testing and it's time for wide exposure, but it's still nice to be able
to fall back to the old implementation for testing when a problem comes
along. Eventually the option and the old implementation will go away.
The opportunity now exists to move a whole lot of boilerplate from all the
arm kernel config files into std.arm*, but that's a commit for another day.
