[PATCH v12 0/7] ARM: kprobes: OPTPROBES and other improvements.

[Wang Nan]

This is v12 of optprobe related patch series. In this series, code in
optprobe is improvemented; the kprobe related files names are changed
to represent their functions.

Patch 1/7 moves all ARM probe related code to arch/arm/probes according
to suggestion from Russell King and Masami Hiramatsu.

Patch 2/7 - 5/7 introduce checker framework and use it to detect stack
consumption for each probed instructions.

Patch 6/7 and 7/7 are for real optprobe work.
