From cccd7d46b541d365a3cb1a87946a7fc30cf8e858 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Fri, 25 Jan 2013 10:07:25 +0000 Subject: [PATCH] x86, efi: Set runtime_version to the EFI spec revision commit 712ba9e9afc4b3d3d6fa81565ca36fe518915c01 upstream. efi.runtime_version is erroneously being set to the value of the vendor's firmware revision instead of that of the implemented EFI specification. We can't deduce which EFI functions are available based on the revision of the vendor's firmware since the version scheme is likely to be unique to each vendor. What we really need to know is the revision of the implemented EFI specification, which is available in the EFI System Table header.
