...ing related to
interrupt handling or virtual CPU management.
For now, CommonHV is only applicable to the x86 platform.
Discovery
---------
A CommonHV hypervisor MUST set the hypervisor bit (bit 31 in CPUID.1H.0H.ECX)
and provide the CPUID leaf 4F000000H, containing:
* CPUID.4F000000H.0H.EAX = max_commonhv_leaf
* CPUID.4F000000H.0H.EBX = 0x6D6D6F43
* CPUID.4F000000H.0H.ECX = 0x56486E6F
* CPUID.4F000000H.0H.EDX = 0x66746e49
EBX, ECX, and EDX form the string "CommonHVIntf" in little-endian ASCII.
max_commonhv_leaf MUST be a number between 0x4F000000 and 0x4FFFFFFF. It
