ARM: 7742/1: topology: export cpu_topology
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.
