We should add runtime detection support later.
I'd really like to see runtime detection with this. Effectively not
supporting this on 32-bit sucks, and doing it this way will encourage

flags hurt performance in general (in my testing, at least).
This patch, as-is without runtime detection, benefits platform-specific
Linux builds such as ChromiumOS. Seeing that the patch benefits
immediately for some distros, I see no reason to block the patch for lack
of runtime detection.
I would also like to see runtime detection as a follow-up.
Patch 1 is

By the way, I tested this series by playing around on ChromiumOS,
but I don't believe that warrants a Tested-by.
