Subject: [PATCH 79/93] x86/Sandy Bridge: Sandy Bridge workaround depends on CONFIG_PCI

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

------------------

From: "H. Peter Anvin" <hpa@...ux.intel.com>

commit e43b3cec711a61edf047adf6204d542f3a659ef8 upstream.

early_pci_allowed() and read_pci_config_16() are only available if
CONFIG_PCI is defined.
