--- Comment #9 from Andy Lutomirski <luto at kernel dot org> ---
I'm a bit late to the party, but this patch seems dubious to me.
__get_cpuid_max() fails to distinguish between CPUs that have max level 0
(although I doubt that any such CPUs exist) and CPUs that don't have CPUID at
all.
Shouldn't __get_cpuid_max return -1 if CPUID isn't there or, alternatively,
just generally return the last level + 1 (and 0 if CPUID isn't there)?
