Also:

    The extended state subleaves (EAX=0Dh, ECX=n, n>1).ECX[1]
    indicate whether the extended state component locates
    on the next 64-byte boundary following the preceding state
    component when the compacted format of an XSAVE area is
    used.

    Right now, they are all zero because no supported component
    needed the bit to be set, but the upcoming AMX feature will
    use it.  Fix the subleaves value according to KVM's supported
    cpuid.
