* 2) The special case where the includer provides XEN_CPUFEATURE() in scope.

* Special: '!'
* This bit has special properties and is not a straight indication of a

* Applicability to guests: 'A', 'S' or 'H'
* 'A' = All guests.
* 'S' = All HVM guests (not PV guests).
* 'H' = HVM HAP guests (not PV or HVM Shadow guests).
