A per-CPU batch struct is activated when entering lazy MMU mode; its

leaving the mode). Preemption is disabled in that interval to ensure
that the per-CPU reference remains valid.
The generic lazy_mmu layer now tracks whether a task is in lazy MMU
mode. We can therefore use the generic helper in_lazy_mmu_mode()
to tell whether a batch struct is active instead of tracking it
explicitly.

I suspect you were not able to test this on real HW. Some help from the
ppc folks would be appreciated.
LGTM, but the interaction with pause/resume adds a bit of complication
on top.
