[PATCH] Check enabled field of processor affinity

Hi there,

I think that acpi_numa_processor_affinity_init() should check the
enabled field of processor affinity because ACPI spec says "If clear,
the OSPM ignores the contents of the Processor Local APIC/SAPIC
Affinity Structure".

Thanks,
Keiichiro Tokunaga
