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.
