By deleting unused code, this makes perfmon irq handling more efficient,
as well as reducing code size.

* remove unused pfm_install_alt_pmu_interrupt()
* remove unused pfm_remove_alt_pmu_interrupt()

I have not problem with the patch except maybe for those two functions.
How do you know they are not used?
Have you checked the VTUNE open-source driver?
I thought at some point they were using this hook.

I was hoping some IA-64 person could speak authoritatively on the subject :)
