Currently in hpte_need_flush() if there is no batch pending we always do a global TLB flush, which is inefficient if the mm has never run on another thread. Instead do the same check that __flush_tlb_pending() does and check if a local flush is sufficient when batch->active is false. Instead of open-coding it we use mm_is_thread_local(). Signed-off-by:
