Better late than never, here is a brief summary of the changes that are
sitting in the sh queue for 2.6.29.

There is the usual batch of new boards, CPU subtypes, and so on. The main
issues of note are:

- dynamic ftrace
- move to generic kgdb stub
- tracehook support for sh64
- optimized bitops for SH-2A
- optimized unaligned accesses on SH-4A
- optimized mutex fastpath on SH-4A
- clock framework support for the SH-Mobile CPUs and their
respective drivers
- Killing off the libgcc linking, making it easier to build a
wider range of kernels with a wider range of toolchains

and lots of other things all over the place that I won't bother
enumerating.

The tree is at:

git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6.git
