This patch set adds KProbs, JProbs and KRetProbes support for the MIPS archetecture. It was tested on a 64-bit big-endian kernel (Octeon), but should work equally well on 32-bit and little-endian as well. As you can see from the patches it is partially based on previous work by Sony and Himanshu Chauhan.
