But for extended topology levels, Intel CPU (in CPUID[0x1F]) and AMD CPU (in CPUID[0x80000026]) have the different definitions with different enumeration values. Though CPUID[0x80000026] hasn't been implemented in QEMU, to avoid possible misunderstanding, split topology types of CPUID[0x1F] from the definitions of CPUID[0xB] and introduce CPUID[0x1F]-specific topology types.
