With SVM the TLB supports tagging to distinguish TLB entries from
different virtual CPUs. This tag is called an ASID. The amount of ASIDs is
given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might
break hypervisors. Let's better return something >0 here, say 0x10.
Since we're flushing the complete TLB on every VM entry and exit we're not
making use of the ASID information anyways.
