[MIPS] Reduce race between cpu_wait() and need_resched() checking
...
If a thread became runnable between need_resched() and the WAIT
instruction, switching to the thread will delay until a next interrupt.
Some CPUs can execute the WAIT instruction with interrupt disabled, so
we can get rid of this race on them (at least UP case).
Original Patch by Atsushi with fixing up for MIPS Technology's cores by
Ralf based on feedback from the RTL designers.

No point in checking cpu_has_tlb before we've computed the CPU options.

So for now we just unconditionally set the option - Linux wouldn't
work without a TLB anyway.
Setting MIPS_CPU_4KTLB was missing for Alchemy and Sandcraft, add that
back.

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!
