Help text

s390 and alpha require percpu variables in modules to be defined weak to work around addressing range issue which puts the following two restrictions on percpu variable definitions.

1. percpu symbols must be unique whether static or not 2. percpu variables can't be defined inside a function

To ensure that generic code follows the above rules, this option forces all percpu variables to be defined as weak.
