    Subject[PATCH v2 18/66] KVM: x86: Use common loop iterator when handling CPUID 0xD.N
    Date
    Use __do_cpuid_func()'s common loop iterator, "i", when enumerating the
    sub-leafs for CPUID 0xD now that the CPUID 0xD loop doesn't need to
    manual maintain separate counts for the entries index and CPUID index.

    No functional changed intended.
