sparc: mmu_gather rework
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.
