[PATCH] CPUID bug and inconsistency fix
The recent support for K8 multicore was misported from x86-64 to i386, due to an unnecessary inconsistency between the CPUID code. Sure, there is are no x86-64 VIA chips yet, but it should happen eventually. This patch fixes the i386 bug as well as makes x86-64 match i386 in the handing of the CPUID array. Signed-off-by: H.
