Alex Smith 656ff9bef0 MIPS: ptrace: Avoid smp_processor_id() when retrieving FPU IR 
Whenever ptrace attempts to retrieve the FPU implementation register it
accesses it through current_cpu_data, which calls smp_processor_id().
Since the code may execute with preemption enabled, this can trigger
a warning. Fix this by using boot_cpu_data to get the IR instead.
