--- Comment #3 from Roland Scheidegger <sroland at vmware.com> ---
I'm wondering if we actually should use this detection method if the other one
(which queries clflush size in fact) is also available. I guess though there's
some (amd) cpus where the other method isn't available. Not sure what's the
better method to use in any case if both are available (might even provide the
same number on all existing cpus).
Regardless, the patch looks good.
