Merge "percpu: Make __verify_pcu_ptr handle per cpu pointers to arrays"

 * Macro which verifies @ptr is a percpu pointer without evaluating

 * @ptr.  This is to be used in percpu accessors to verify that the

 * input parameter is a percpu pointer.

 *

 * + 0 is required in order to convert the pointer type from a

 * potential array type to a pointer to a single item of the array.
