I don't care, as long as there is some entropy.
I want to add a entropy harvester into the namei cache, and if I can
also pass in some genuine junk, that helps things.
For interrupts, the interrupt number is used; for the keyboard, scancodes;
the available environmental stuff in the namei cache is centred around
vnodes, so I'm looking for dirt in them. Heck - I may just xor the whole
thing into an int to get some junk if necessary.
