kulsinski has been superseded by kulczynski1 in #1484.

As per scipy/scipy#2009 (comment)_, we should deprecate kulsinski starting with 1.9.

Implement GPU version of numpy.* functions in cupy.* namespace.

This is a tracker issue that lists the remaining numpy.* APIs (see also: comparison table). I've categorized them based on difficulty so that new contributors can pick the right task. Your contribution is highly welcomed and appreciated!
