I'm sorry, i should have made myself clearer. What is was trying to
ask was: Are callgraphs available on ARM architectures where the
CPU isn't XScale?

 From studying arch/arm/oprofile/common.c i concluded that the
only ARM CPU which supports callgraphs ATM is XScale.
It's the only architecture for which a spec structure is available.

I'm especially interested if the code in arch/arm/oprofile/backtrace.c
is generic enough to be used with other CPUs?
