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

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

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 92bdd3f5eba299b33c2f4407977d6fa2e2a6a0da ]

The cpu_topology symbol is required by any driver using the topology
interfaces, which leads to a couple of build errors:

ERROR: "cpu_topology" [drivers/net/ethernet/sfc/sfc.ko] undefined!
ERROR: "cpu_topology" [drivers/cpufreq/arm_big_little.ko] undefined!
ERROR: "cpu_topology" [drivers/block/mtip32xx/mtip32xx.ko] undefined!

The obvious solution is to export this symbol.
