Hi Max,

I have applied your patches except for the MMU v3 patch. It feels that
it needs a bit more clean-up, but I need to go through it more
thoroughly to be sure. For example, it's about MMU, but the description
only talks about GDB. The comments in general feel overwhelming.
Although, they maybe necessarily need to be. I'll get back to you on
this one.

Thanks,
-Chris
