Thanks a lot for catching this.  gcc 4.4.1 building for x86_64 doesn't
seem to notice that.  gcc has been relatively reliable in catching
these mistakes.  I wonder what made it slip.  My cross gcc 4.3.3 for
powerpc catches it.  Strange.  Anyways, fix folded into
0035-workqueue-implement-several-utility-APIs.patch

Thank you.
