This is completely bogus. That patch does not even affect anything outside
of the SGI UV platform. And on your i7 system uv_bios_call() is definitely
not invoked.

I appreciate your effort, but posting such obviously bogus results does not
make people more confident in your testing efforts.

Thanks,
