Victor Sun 363daf6aa2 HV: return extended info in vCPUID leaf 0x40000001
In some case, guest need to get more information under virtual environment,
like guest capabilities. Basically this could be done by hypercalls, but
hypercalls are designed for trusted VM/SOS VM, We need a machenism to report
these information for normal VMs. In this patch, vCPUID leaf 0x40000001 will
be used to satisfy this needs that report some extended information for guest
by CPUID.
