This is version 11 of optprobe related patch series. I decide to merge
all related patches in one series to make my work easier. This series is
grouped by 3 different parts:

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

Patch 2/7 - 5/7 introduce checker framework and use it to detect stack
consumption for each probed instructions. Previous discussion can
be found from:

Patch 6/7 and 7/7 are for real optprobe work. Previous discussion can
be found from:

The main modifications in this series are reside in patch 7/7. Please refer
to its own commit message.
