We do not need to references arguments just to avoid compiler warnings, the warning in question does not arise here, so remove all of the instances of '(void)xxx' introduced purely to avoid this warning. As reported by WagYuli in the referenced mail, GCC 8.3 and before will have issues compiling this file if parameter names are not provided, so ensure these are always provided. Finally, perform a trivial fix up of kmem_cache_alloc() which technically has parameters in the incorrect order (as reported by Vlastimil Babka off-list).
