patch

obsolete

>From: Thomas Rosner <kernel-bugs@digital-trauma.de>
>
>This adds all known BIOS versions of IBM R40e Laptops to the C2/C3
>processor state blacklist and thus prevents them from crashing.  Fixes Bug
>#3549.
>
>Implementation is probably overly verbose, but DMI_MATCH seems to give us
>no choice.
