percpu: cleanup percpu array definitions
Currently, the following three different ways to define percpu arrays are in use. 1. DEFINE_PER_CPU(elem_type[array_len], array_name); 2. DEFINE_PER_CPU(elem_type, array_name[array_len]); 3. DEFINE_PER_CPU(elem_type, array_name)[array_len]; Unify to #1 which correctly separates the roles of the two parameters and thus allows more flexibility in the way percpu variables are defined.
