You can definitely enable ia64 support for oprofile even without perfmon. Are you saying the end result isn't usable? Because I'd be inclined to just remove CONFIG_PERFMON support, and see if anybody even notices.. I'm not expecting a lot of people to do a lot of oprofile on ia64 anyway. It's a bit late to start optimizing things now. Do people use perfmon still? Maybe. Maybe not. Perhaps we could just mark it as broken in the Kconfig file for now, and see if somebody says something?
