This follows the sparc changes a439fe51.

Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.

Currently the wdt forces HZ=1000 and sidesteps CONFIG_HZ completely. This
is a remnant from when HZ was hardcoded and before CONFIG_HZ was
introduced. Additionally, not all of the timers have this requirement
these days, so it's also an artificial limitation. Just kill it off and
use CONFIG_HZ directly.

This wasn't being set before, so now it's set for when it makes sense.
The shwdt case still requires HZ to be fixed at 1000 for the WOVF period,
so this is still preserved.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
