- Don't always pass the cpuid request to the current CPU as some nodes we will emulate purely in software. - Pass in the APIC ID of the virtual CPU so we can return the proper APIC ID. - Always report a completely flat topology with no SMT or multicore. - Report the CPUID2_HV feature and implement support for the 0x40000000 CPUID level. - Use existing constants from <machine/specialreg.h> when possible and use cpu_feature2 when checking for VMX support.
