See 'src/testsuite/systemtap.stress/all_kernel_functions.exp'.
This test is not enabled in the normal test-runs, because of the
likelyhood of inducing crashes. There's an 'if 0' near the bottom that
gates the test, so just flip that to try it out.
The 'genload' function in the test could probably be improved to get a
more representative kernel test...
