Two to the power of a negative number is equivalent to dividing by two
to the power of said exponent's absolute value, making this paragraph
more than a bit confusing - indeed, a literal read would make it
equivalent to multiplying by 2^abs(oom_adj).
I would think that the following would be enough:
* The resulting score is multiplied by two to the power of oom_adj.
Unless we assume admins don't know how exponentiation by a negative
number works :)
