What happens if you do that and why is x86 not selecting it in general?Erm, "selecting it in general" (well at least on x86) is what this patch is doing.Sorry that I was unclear, what I meant to say is why wasn't this done ages ago since so many important architectures seem to have it enabled by default. I suppose the reason would be something like "firmware/BIOS should handle that for us" and recently that has started to break apart and x86 platforms started to be more like ARM?
That (x86 becoming more like ARM, sorta, kinda) as well as that turning it on on x86 was not safe until Thomas wrote the 2 patches which are marked as dependencies in the commit message for this patch. Regards, Hans
