Building on the work of Christophe, Aneesh and Balbir, I've ported KASAN to Book3S radix.
It builds on top Christophe's work on 32bit, and includes my work for 64-bit Book3E (3S doesn't really depend on 3E, but it was handy to have around when developing and debugging). This provides full inline instrumentation on radix, but does require that you be able to specify the amount of memory on the system at compile time. More details in patch 7.
