Tag all armv7 kernels as such in their machine config line. 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. Differential Revision: https://reviews.freebsd.org/D12027

With r181803 on 2008-08-17 23:27:27Z the first VIMAGE commit went into 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.

Make 'device crypto' lines more consistent. - 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. Reviewed by: rgrimes, cem, imp Differential Revision: https://reviews.freebsd.org/D16775

Remove IPSEC from GENERIC due to performance issues Having IPSEC compiled into the kernel imposes a non-trivial performance penalty on multi-threaded workloads due to IPSEC refcounting. In my benchmarks of multi-threaded UDP transmit (connected sockets), I've seen a roughly 20% performance penalty when the IPSEC option is included in the kernel (16.8Mpps vs 13.8Mpps with 32 senders on a 14 core / 28 HTT Xeon 2697v3)). This is largely due to key_addref() incrementing and decrementing an atomic reference count on the default policy. This cause all CPUs to stall on the same cacheline, as it bounces between different CPUs. Given that relatively few users use ipsec, and that it can be loaded as a module, it seems reasonable to ask those users to load the ipsec module so as to avoid imposing this penalty on the GENERIC kernel. Its my hope that this will make FreeBSD look better in "out of the box" benchmark comparisons with other operating systems. Many thanks to ae for fixing auto-loading of ipsec.ko when ifconfig tries to configure ipsec, and to cy for volunteering to ensure the the racoon ports will load the ipsec.ko module Reviewed by: cem, cy, delphij, gnn, jhb, jpaetzel Differential Revision: https://reviews.freebsd.org/D20163
