On Arndale board, perf works well on llct as well as Samsung topic
tree, but fails on linux-linaro. Git bisect points to commit
6fea652c638e "ARM: perf: [WIP] Add register emulation for offline ARMv7
Is there anything missing w.r.t. Arndale/Exynos to get perf to work on
> This patch series adds basic uprobes support to ARM. It is based on patches developed earlier by Rabin Vincent. That approach of adding special cases into the kprobes instruction parsing code was not well received. This approach separates the ARM instruction parsing code in kprobes out into a separate set of functions which can be used by both kprobes and uprobes. Both kprobes and uprobes then provide their own semantic action tables to process the results of the parsing.
> Some regression bug fixing is still in progress on this, and some more definitions may be moved from kprobes*.h files into more generic include files. However, at this point feedback on the basic approach would be appreciated.
> These patches are based on v3.10-rc3

Could you provide unit test cases to test these patches ?
