But that wouldn't be ideal as we want the page tables above kernel image and the above would allocate it above ISA_END_ADDRESS, right? Maybe memory_map_bottom_up() should take extra parameters for where to allocate page tables at separately from the mapping range and treat it specially? Would that make the function a lot more complex? Thanks. -- tejun -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
