ppc32 linux preloads entries into the hashed pagetable in update_mmu_cache. Im about to commit a patch to do the same thing in ppc64, at the moment we take two exceptions per pagefault which is pretty ugly.
Some ppc32 hardware does allow you to take an exception for a TLB miss (ie bypass the hashed pagetable completely).
