3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 92bdd3f5eba299b33c2f4407977d6fa2e2a6a0da upstream.
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.
