Shouldn't the same check for level type be applied for SMT as well?

```
for (level = 0; ; level++) {
    cpuid_regs = cpuid_ext(cpu_id_op, level);
    if (CPUID_LEVEL_TYPE(level) == INVALID)
          break;

switch (CPUID_LEVEL_TYPE(level)) {
          case SMT:
               thread_bits = cpuid_regs.eax & CPUID_CPU_TOPOLOGY_LEVEL_BITS_MASK;
               break;
          case CORE:
               core_bits = cpuid_regs.eax & CPUID_CPU_TOPOLOGY_LEVEL_BITS_MASK;
               break;
          default:
               break;
    }
}

thread_shift = 0;
thread_mask = BIT(thread_bits) - 1;

core_shift = thread_bits;
core_mask = BIT(core_bits - thread_bits) - 1;

package_shift = core_bits;
```
