Just to clarify my point to Nilay about no functional physical memory. We need
to make this configurable. There are plenty of protocols that exist, include
many at AMD, that still rely on a separate copy of functional physical memory.
Thanks,
Brad

Hi Nilay,
Thanks for the feedback. I merely wanted to avoid as much rebasing as possible,
and your patches feed nicely into some of the memory cleanups that are ongoing
on our side.

This is going to take sometime. Brad and I had a chat two weeks back
and there is some work that I need to do. I am currently unsure how
soon I would it, probably another week or so.
Am I blocking any of your patches?
Thanks
Nilay

Would be good to get this and the other Ruby/memory system
interaction patches out there.

ruby: no functional physical memory
This patch removes the functional copy of memory that was in place
for ruby fs simulations. All the memory accesses now source and
sink values to the memory maintained by ruby.
