That technique was used in some of my U of Toronto friends' PhD thesis
research & projects:

"Managing Shared L2 Caches on Multicore Systems in Software"

"Reducing the Harmful Effects of Last-Level Cache Polluters with an
OS-Level, Software-Only Pollute Buffer"

http://www.eecg.toronto.edu/~tamda/

IIRC, all those techniques are OS only, with no changes to the CPU MMU
or cache mapping logic.
