Linux-2.6.12-rc2v2.6.12-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!

+ *        on failure.
+ * @mark_offset: called by the timer interrupt.
+ * @get_offset:  called by gettimeofday(). Returns the number of microseconds
+ *               since the last timer interupt.
+ * @monotonic_clock: returns the number of nanoseconds since the init of the
+ *                   timer.
