Cover letter [PATCH 0/5] ARM: kprobes: Fixes and additions for ARM instruction emulation (part 6)

(This is a sixth and final set of patches)
When kprobes are inserted into code an ARM instruction is replaced by a breakpoint. When this is hit, the original instruction must be emulated out-of-line. This patchset fixes some bugs in the instruction decoding and adds emulation for some newer ARMv7 instructions.

I notice that Nicolas merged the 5th set rather than this set - and Nicolas hasn't responded to these. Please check with Nicolas whether he's updated to the latest set.
Nicolas, I see you have part 6 in your personal Linaro kprobes branch, but Russell seems to imply that this is missing from a merge you did elsewhere. (I'm unsure where this merge might be.)
