kernel absolutely should not care much about SMBIOS(DMI info),
AFAIK, every BIOS vendor did not fill accurate info in SMBIOS,
mostly only on demand when OEMs required SMBIOS to report some
specific info.
furthermore, SMBIOS is so old and benifit nobody(in my personal
opinion), so maybe let's forget it.
