You are right. I removed this patch and still see no change in
behaviour. Earlier without this patch, I saw that perf report
would show a wrong function name(around 2.6.34-rc5 and I carried it
to 2.6.35-tip). However the number of events recorded would
correspond to the probed function.

Since I am seeing correct behaviour even without this patch, I
will drop this patch in the next posting of the patchset.
