/**
  CPUID Extended Topology Information

  @note
  CPUID leaf 1FH is a preferred superset to leaf 0BH. Intel recommends first
  checking for the existence of Leaf 1FH before using leaf 0BH.
  Most of Leaf 0BH output depends on the initial value in ECX.  The EDX output
  of leaf 0BH is always valid and does not vary with input value in ECX.  Output
  value in ECX[7:0] always equals input value in ECX[7:0].
  Sub-leaf index 0 enumerates SMT level. Each subsequent higher sub-leaf index
  enumerates a higher-level topological entity in hierarchical order.
  For sub-leaves that return an invalid level-type of 0 in ECX[15:8]; EAX and
  EBX will return 0.
  If an input value n in ECX returns the invalid level-type of 0 in ECX[15:8],
  other input values with ECX > n also return 0 in ECX[15:8].

  CPUID Deterministic Address Translation Parameters

  @note
  Each sub-leaf enumerates a different address translation structure.
  If ECX contains an invalid sub-leaf index, EAX/EBX/ECX/EDX return 0. Sub-leaf
  index n is invalid if n exceeds the value that sub-leaf 0 returns in EAX. A
  sub-leaf index is also invalid if EDX[4:0] returns 0.
  Valid sub-leaves do not need to be contiguous or in any particular order. A
  valid sub-leaf may be in a higher input ECX value than an invalid sub-leaf or
  than a valid sub-leaf of a higher or lower-level structure.
  * Some unified TLBs will allow a single TLB entry to satisfy data read/write
  and instruction fetches. Others will require separate entries (e.g., one
  loaded on data read/write and another loaded on an instruction fetch).
  Please see the Intel 64 and IA-32 Architectures Optimization Reference Manual
  for details of a particular product.
  ** Add one to the return value to get the result.

/**
  CPUID V2 Extended Topology Enumeration Leaf

  @note
  CPUID leaf 1FH is a preferred superset to leaf 0BH. Intel recommends first checking
  for the existence of Leaf 1FH and using this if available.
  Most of Leaf 1FH output depends on the initial value in ECX. The EDX output of leaf
  1FH is always valid and does not vary with input value in ECX. Output value in ECX[7:0]
  always equals input value in ECX[7:0]. Sub-leaf index 0 enumerates SMT level. Each
  subsequent higher sub-leaf index enumerates a higher-level topological entity in
  hierarchical order. For sub-leaves that return an invalid level-type of 0 in ECX[15:8];
  EAX and EBX will return 0. If an input value n in ECX returns the invalid level-type of
  0 in ECX[15:8], other input values with ECX > n also return 0 in ECX[15:8].

  Software should use this field (EAX[4:0]) to enumerate processor topology of the system.
  Software must not use EBX[15:0] to enumerate processor topology of the system. This value
  in this field (EBX[15:0]) is only intended for display/diagnostic purposes. The actual
  number of logical processors available to BIOS/OS/Applications may be different from the
  value of EBX[15:0], depending on software and platform hardware configurations.
