My static checker complains that we put an upper bound on the "size"
argument but not a lower bound. The checker is not smart enough to know
the possible ranges of "old_mm->context.ldt->size" from
init_new_context_ldt() so it thinks maybe it could be negative.
Let's make it unsigned to silence the warning and future proof the code
a bit.
