Subject: [PATCH 3.12 116/122] x86/early quirk: use gen6 stolen detection for VLV

From: Jesse Barnes <jbarnes@...tuousgeek.org>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 7bd40c16ccb2cb6877dd00b0e66249c171e6fa43 upstream.

We've always been able to use either method on VLV, but it appears more
recent BIOSes only support the gen6 method, so switch over to that.
