[PATCH] switch_mm and enter_lazy_tlb: remove cpu arg
switch_mm and enter_lazy_tlb take a CPU arg, which is always
smp_processor_id(). This is misleading, and pointless if they use
per-cpu variables or other optimizations. gcc will eliminate
redundant smp_processor_id() (in inline functions) anyway.
This removes that arg from all the architectures.
