I had a link to the commit that integrates rampup multiplier [1]. The utility
is in my github [2] at the moment. I am hoping, if we all agree it is the right
thing to do, to move it to kernel.org and get the development on the list.

I yet to introduce how to manage cookies there FWIW. I still need to spend more
time to bring it to full shape.. I plan to add support to help Tim and Chen to
easily tag QOS_MEM_DEP (or whatever name we choose) tasks/processes so that can
help with driving how cache aware support can be added and managed by this
service. And give us more confidence in the interface and overall concept.

It'd be reassuring to know if it's moving in the right direction or not before
I sink more time on it :)
