The other team here at Mentor Graphics, that originally created this set of
tracepoints instrumentation, submitted them to the list quite long ago.
Also, they actually did an extensive testing (much more than I was aware of),
including other platforms (e.g. PowerPC).

May be it's not too late to still include at least the original implementation
of tracepoints (may be with some later fixes) to upcoming 2.1 release?
Having new supported fixed kernel tracepoints could be a good accomplishment
for the release.

Thanks.

Best regards,
