Well I think the best is just not do any of this. One can already do
k[zm]alloc(x * sizeof(struct whatever)). Do x*x for 2 dimensions etc etc.
No need to change the API.

If you add these variants then please think
about the necessity to add other variants (like the kmalloc_node() NUMA
call) etc in the future.
