The patch titled
DMI: Decode and save OEM String information
has been added to the -mm tree. Its filename is
dmi-decode-and-save-oem-string-information.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: DMI: Decode and save OEM String information
From: "Shem Multinymous" <multinymous@xxxxxxxxx>
This teaches dmi_decode() how to decode and save OEM Strings (type 11) DMI
information, which is currently discarded silently. Existing code using
DMI is not affected. Follows the "System Management BIOS (SMBIOS)
Specification" (http://www.dmtf.org/standards/smbios), and also the
userspace dmidecode.c code.
OEM Strings are the only safe way to identify some hardware, e.g., the
ThinkPad embedded controller used by the soon-to-be-submitted tp_smapi
driver. This will also let us eliminate the long whitelist in the mainline
hdaps driver (in a future patch).
