SMBIOSv3 is absent in k3.18.
I simply chekcouted on v3.18 and verified.
There were no SMBIOSv3 support added.
Patch points on SMBIOSv3, no SMBIOSv3 - no need in patch.

Ivan,
Why so? The commit description/code doesn't really make that clear.
Thanks,
Sasha

Sasha,
There is no need in this patch for 3.18, only beginning from 3.19.

This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 6d9ff473317245e3e5cd9922b4520411c2296388 ]
According to SMBIOSv3 specification the length of DMI table can be
up to 32bits wide. So use appropriate type to avoid overflow.
It's obvious that dmi_num theoretically can be more than u16 also,
so it's can be changed to u32 or at least it's better to use int
instead of u16, but on that moment I cannot imagine dmi structure
count more than 65535 and it can require changing type of vars that
work with it. So I didn't correct it.
