Subject: [PATCH v6 1/2] sparc: fix a building error reported by kbuild

>> arch/sparc/include/asm/topology_64.h:44:44:
error: implicit declaration of function 'cpu_data'
[-Werror=implicit-function-declaration]

 #define topology_physical_package_id(cpu) (cpu_data(cpu).proc_id)
                                               ^
Let's include cpudata.h in topology_64.h.
