Subject: [PATCH 0/5] KProbes support for MIPS

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.

David Daney (5):
  MIPS: Define regs_return_value()
  MIPS: Add instrunction format for BREAK and SYSCALL
  MIPS: Add KProbe support.
  samples: kprobe_example: Make it print something on MIPS.
  documentation: Mention that KProbes is supported on MIPS
