From b53d27ff66e343520df4d287c419235fbe6e3fea Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Sat, 24 Apr 2010 09:56:53 +0200 Subject: [PATCH] x86, k8: Fix build error when K8_NB is disabled commit ade029e2aaacc8965a548b0b0f80c5bee97ffc68 upstream. K8_NB depends on PCI and when the last is disabled (allnoconfig) we fail at the final linking stage due to missing exported num_k8_northbridges. Add a header stub for that.
