used as it forces an exact (power of two) size of the ring buffer.
The number of possible CPUs is used for this computation ignoring
- hotplugging making the compuation optimal for the the worst case
- scenerio while allowing a simple algorithm to be used from bootup.
+ hotplugging making the computation optimal for the worst case
+ scenario while allowing a simple algorithm to be used from bootup.
Examples shift values and their meaning:
17 => 128 KB for each CPU
