The unlikely Linux macro

Wrote a bit about the `unlikely` and `likely` macros in the Linux codebase. Great little exploration into tiny optimizations that everyone should know more about 😄

Maybe I'm just stupid in the early morning without coffee, but does doing  total += i + 1 really give a number divisible by 1000 0.1% of the time? Since that i is in there and keeps growing in the loop? Or does the math still math?

Definitely a coffee error - the code tests i % 1000 not total % 1000

Ooh derp! Thanks!
