Nicholas Piggin 032b7f0893 powerpc/64s/radix: serialize_against_pte_lookup IPIs trim mm_cpumask 
serialize_against_pte_lookup() performs IPIs to all CPUs in mm_cpumask.
Take this opportunity to try trim the CPU out of mm_cpumask. This can
reduce the cost of future serialize_against_pte_lookup() and/or the
cost of future TLB flushes.
