Reading the KVM_CAP_MIPS_FPU capability returns cpu_has_fpu, however this uses smp_processor_id() to read the current CPU capabilities (since some old MIPS systems could have FPUs present on only a subset of CPUs). We don't support any such systems, so work around the warning by using raw_cpu_has_fpu instead. We should probably instead claim not to support FPU at all if any one CPU is lacking an FPU, but this should do for now.
