+If the processor is vulnerable then the following information is appended to +the above information:

• 'SMT vulnerable' SMT is enabled

Why is list-table used in sysfs table instead of usual ASCII table in SMT vulnerabilities list above? I think using ASCII table in both cases is enough for the purpose.
