> Rework the sparc mmu_gather usage to conform to the new world order :-)
>
> Sparc mmu_gather does two things:
> - tracks vaddrs to unhash
> - tracks pages to free
>
> Split these two things like powerpc has done and keep the vaddrs
> in per-cpu data structures and flush them on context switch.
>
> The remaining bits can then use the generic mmu_gather.
