Subject: [27/39] x86, k8: Fix build error when K8_NB is disabled


2.6.33-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Borislav Petkov <borislav.petkov@....com>

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.
