Let's just remove it completely. I have yet to see a bug because of it,
and we have 0x40 byte cache lines.
If anything, compare firmware setting to cputable one and print a warning.
Should maybe give them loglevels too, since you're touching them? I
suggest KERN_DEBUG -- if needed it's there in dmesg, and if you need it
on the console you can just add "debug" to the kernel command line.
