That patch used to just add a hook to page table flushing but pulling that string brought out a whole bunch of issues, so it now does that and more: - We now make the RCU batching of page freeing SMP only, as I believe it was intended initially. We make a few more things compile to nothing on !CONFIG_SMP - Some macros are turned into functions, though that forced me to out of line a few stuffs due to unsolvable include depenencies, however it's probably better that way anyway, it's not -that- critical code path. - 32-bit didn't call pte_free_finish() on tlb_flush() which means that it wouldn't push out the batch to RCU for delayed freeing when a bunch of page tables have been freed, they would just stay in there until the batch gets full. 64-bit BookE will use that hook to maintain the virtually linear page tables or the indirect entries in the TLB when using the HW loader.
