First of all, thanks so much for writing your futex test suite, it's proved invaluable for sparc64 kernel development for me lately.
I'd like to suggest that you add a test that triggers transparent hugepages, because if an architecture doesn't implement __get_user_pages_fast() such futexes cause a machine to hang. I hacked up something simple that took the existing performance test and made it operate in a register allocated using memalign(). I would suggest doing a memalign(HUGEPAGE_SIZE, HUGEPAGE_SIZE) then iterating running a futex test within each normal page within that hugepage.
