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.
