I think it probably makes sense to do this as a combined cleanup patch,
which I can merge through the asm-generic tree, for all architectures
whose maintainer does not pick it up directly. For SMP architectures,
it's a bugfix that we probably want backported into stable kernels, while
for non-SMP targets it is just a minor cleanup for consistency.
