module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Signed-off-by: Rusty Russell

This patch cleans and simplifies kvm_dev_ioctl_get_supported_cpuid by using a table

Intel latest cpu add 6 new features, refer http://software.intel.com/file/36945
The new feature cpuid listed as below: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.
