1. FMA CPUID.EAX=01H:ECX.FMA[bit 12]
2. MOVBE CPUID.EAX=01H:ECX.MOVBE[bit 22]
3. BMI1 CPUID.EAX=07H,ECX=0H:EBX.BMI1[bit 3]
4. AVX2 CPUID.EAX=07H,ECX=0H:EBX.AVX2[bit 5]
5. BMI2 CPUID.EAX=07H,ECX=0H:EBX.BMI2[bit 8]
6. LZCNT CPUID.EAX=80000001H:ECX.LZCNT[bit 5]
This patch expose these features to guest.
Among them, FMA/MOVBE/LZCNT has already been defined, MOVBE/LZCNT has
already been exposed.
This patch defines BMI1/AVX2/BMI2, and exposes FMA/BMI1/AVX2/BMI2 to guest.
