[Pete L. <pet...@st...>]

I do understand that the kernel source does not welcome C++, unfortunately,
that's the way the driver source was given to me when I was asked to get it
running on an SH4 dev board.
If there is no hope of getting the C++ driver linked to the kernel, I'll go
back to trying to get profiling data out of a loadable module.
thanks for the information.
