in other words, no kernel support is required, and the hardware acts 
as you'd expect (as a cache).  if you happen to want it to restrict it 
to only accelerating the onchip GPU, a kernel option is now available. 
the topic was in using it for general HPC acceleration, not GPU, no?

it would be an interesting knob to have for openCL code...
