d887ab3a9b [SPARC64]: Provide mmu statistics via sysfs. 
If the system supports hypervisor based statistics, allow them to
be fetched, enabled, and disabled via sysfs.

Enable and disable via the boolean:

/sys/devices/systems/cpu/cpuN/mmustat_enable

Statistic values are provided under:

/sys/devices/systems/cpu/cpuN/mmu_status/

eff3414b72 [SPARC64]: Move topology init code into new file, sysfs.c 
Also, use per-cpu data for struct cpu.  Calling kmalloc for
each cpu in topology_init() is just plain clumsy.
