The generic lazy_mmu layer now tracks whether a task is in lazy MMU mode. As a result we no longer need to track whether the per-CPU TLB batch struct is active - we know it is if in_lazy_mmu_mode() returns true.
It's worth adding that disabling preemption while enabled makes sure that we cannot reschedule while in lazy MMU mode, so when the per-CPU TLB batch structure is active. -- Cheers David / dhildenb
