[PATCH] md: remove a number of misleading calls to MD_BUG

The conditions that cause these calls to MD_BUG are not kernel bugs, just
oddities in what userspace is asking for.

Also convert analyze_sbs to return void, and the value it returned was
always 0.

[PATCH] md: close a small race in md thread deregistration

There is a tiny race when de-registering an MD thread, in that the thread
could disappear before it is set a SIGKILL, causing send_sig to have
problems.

This is most easily closed by holding tasklist_lock between enabling the
thread to exit (setting ->run to NULL) and telling it to exit.

(akpm: ick. Needs to use kthread API and stop using signals)

Linux-2.6.12-rc2

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!
