If we take this "goto out" path, then we'll miss out on calling
the tlb_finish_mmu() which you deleted just above. At the very
least this will leave preemption disabled (since we'll miss calling
the put_cpu_var(mmu_gathers)).
I think I'm also missing the big picture view of what you are
doing here.
