signed_integer_overflow_check: if (foo + bar < foo) is undefined for signed
If you try to use "if (foo + bar < foo)" then make sure that the addition
is done as unsigned. I don't really know how this affects the kernel or
if it matters with the combination of gcc options we use. But technically
it is incorrect code.
