I don't think that's correct for these two. perf_event_open() of course requires 'perf' support that ia64 does not have
That's actuallt quite funny, given the fact that IA-64 has perfmonctl() which likely was the precursor of current perf infractructure.

One comment for all pkey calls would be sufficient. More importantly it requires hardware support that ia64 does not have AFAICT.
Except it has[1].
