[RFC PATCH 0/2] ARM: kprobes: Table driven decoding of CPU instructions

[Deepak Saxena]

Hi Tixy,

Do you want to also submit this to linux-arm-kernel (cc: linaro-kernel
and linaro-dev)?
I think it'd be good to get input directly from upstream folks (rmk in
particular) on
the first pass.

Thanks,
~Deepak
