[ Upstream commit 2b7ec33e534f7a10033a5cf07794acf48b182bbe ]
Use raw_smp_processor_id() instead of plain smp_processor_id() in do_service_request(), otherwise we may get some errors with the driver enabled:
BUG: using smp_processor_id() in preemptible [00000000] code: (udev-worker)/208 caller is loongson3_cpufreq_probe+0x5c/0x250 [loongson3_cpufreq]
