Hi Tiezhu,
You're touching Kernel userspace API and I believe it should be
documented. Also linux-api list
should be informed.
[RESEND due to the following reason:
Can not connect to recipient's server because of unstable

Hi Jiaxun,
Thanks for your suggestion. I will do it as soon as possible and then
send v2.
Also I'd like to know if it's really useful for mainline kernel.
For user who wants to check board information, dmidecode is already
useful enough.
There is no SMBIOS and dmidecode can see nothing on some machines, like
this:
[root@linux loongson]# dmidecode
# dmidecode 2.12
# No SMBIOS nor DMI entry point found, sorry.
So I think it is useful.
Thanks,
Tiezhu Yang
Thanks.
