Will Deacon 621a0147d5 ARM: 7757/1: mm: don't flush icache in switch_mm with hardware broadcasting ... When scheduling an mm on a CPU where it hasn't previously been used, we flush the icache on that CPU so that any code loaded previously on a different core can be safely executed. For cores with hardware broadcasting of cache maintenance operations, this is clearly unnecessary, since the inner-shareable invalidation in __sync_icache_dcache will affect all CPUs. This patch conditionalises the icache flush in switch_mm based on cache_ops_need_broadcast().
