My core2duo patch introduced a vague statement of "missing features" in

Browse source 
the CPUID specification. This patch addresses this by specifying exactly 
what is missing.
While going along the missing CPUID entries I also stumbled across 
invalid and missing CPUID #defines while comparing them to the Intel 
Documentation. This patch also addresses these. I found them too minor 
to split them up in a separate patch.

Furthermore I looked through CPUID functions > 5 and realized that it 
should be safe to bump the level to 10. I tried booting Linux with that 
and it worked fine.
