Nope. kmalloc uses slab allocator underneath it. So, No addresses will not be 4k aligned. If you care about 4k aligned addresses you should use __get_free_page() rather than kmalloc(). kmalloc's are used for small allocations - think about wastage of memory if we try to place 4k alignment requirements.
