Hi Theodore,

If the real unpredictability is really coming from the interrupts
changing the state of the CPU microarchitecture, the real question is
how many interrupts do you need before you consider things
"unpredictable" to an adequate level of security?  Arguing that we
should turn down the "interrupts per bit of entropy" in
drivers/char/random.c is a much more honest way of having that
discussion.

Please answer on the concerns given in [1] which explains that we cannot allow 
turning that knob in the current implementation.
