Branch predictor maintenance is only required when we are either changing the kernel's view of memory (switching tables completely) or dealing with ASID rollover. Both of these use-cases require subsequent TLB invalidation, which has the relevant barrier instructions to ensure completion and visibility of the maintenance, so this patch removes the instruction barrier from [local_]flush_bp_all.
