Thanks for asking, I did not know Russell's patch process, but Florian
guided me and now it is submitted, see

I tested your patch, and I'm not sure how it can work for you, because
the changes made to the PREFETCH_CTRL register on the data/instruction
prefetch bits are later overridden by changes made to the AUX_CTRL
register.

There's also a patch I sent on May 14th which needs to be applied for this
to work, and fixes the above.

How does your patch handles the fact that the prefetch data and
prefetch instr are cloned between PREFETCH_CTRL and AUX_CTRL ?

It needs my patch.

... in fact, please see all the other L2C patches queued in my tree.
Hauke's patch is designed to be applied on top of these patches, not
to 4.1-rc directly.
