    x86, kvm: correctly access the KVM_CPUID_FEATURES leaf at 0x40000101 · 77f01bdf
    Paolo Bonzini authored
    When Hyper-V hypervisor leaves are present, KVM must relocate
    its own leaves at 0x40000100, because Windows does not look for
    Hyper-V leaves at indices other than 0x40000000.  In this case,
    the KVM features are at 0x40000101, but the old code would always
    look at 0x40000001.
    
    Fix by using kvm_cpuid_base().  This also requires making the
    function non-inline, since kvm_cpuid_base() is static.
