Please make sure that the code builds as a module and that each patch compiles cleanly with W=1 C=1 flags set - build the entire tree first with W=1 C=1 cause there will be extra warning noise, then apply your patches one by one and recompile, there should be no warnings since b53 itself builds cleanly.
