Actually, this is just using the pte_free_fast() and {get,free}_pgd_fast() functions on non-pae machines. Rofl, you can't just do that. The page tables cache caches the kernel mappings and if you don't update them properly on SMP you die.
I am seeing reports of SMP failing with rmap12 but not previous patches. You need to revert this I think. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
