The problem is that even oprofile on ia64 depends on perfmon. We have about four options, none of which are terribly appealing: 1. rm -rf arch/ia64. Bit harsh to do this when hardware is still being produced. 2. rm -rf arch/ia64's support for profiling completely. Would anybody complain? 3. Convert ia64 over to perf interface. Who would do this work? 4. Fix the perfmon kernel and userspace to not assume this insane semantic. Flag day, blah, blah. Gentoo and Debian seem to be the only remaining living ports to Itanium and at least the Debian one is very unofficial.
