Reading the second patch in the series I do not think this one even needed. The
problem in the original code is that
int *res, _res;
...
*res = _res << something;
This is a UB for _res < 0. So, the code should never handle negative numbers to
begin with. That said the existing memparse() can be used directly.
If I missed something, it's because the commit message here is poorly written
in regard to negative number parsing.
