Just to be clear, if my patches are merged it won't break any existing
architectures - it is an optional interface and each architecture must
opt-in. Having said that, I'm sure the maintainers for other
architectures will be looking to move over to the new interface. It
certainly makes sense from a maintenance point of view.

If any problems are discovered with the generic perf-oprofile code
while trying to migrate architectures then they can be fixed. Rather
than trying to accomplish the mamoth task of guessing everybody's
requirements, I decided it would be easier to just get support for SH
and ARM working first and others can follow.
