I must be misunderstanding some of the requirements for
calling stop_machine() because my kernel panics, after
many warnings.

I made the following changes, which call stop_machine() at
the end of smp8759_config_read() to do nothing on cpu 0.

Looking at drivers/char/hw_random/intel-rng.c, they don't
seem to do anything special in the callback...
