38  * Base implementations of per-CPU variable declarations and definitions, where
39  * the section in which the variable is to be placed is provided by the

75  * __pcpu_scope_* dummy variable is used to enforce scope.  It
78  * DECLARE_PER_CPU() is used for the same variable.
80  * __pcpu_unique_* dummy variable is used to enforce symbol uniqueness
106  * Variant on the per-CPU variable declaration/definition theme used for
