As requested, I've modified "singleprocessor" to "uniprocessor" in my tree, and the revised patch is included below (with the Signed-off-by at the right end this time - thanks Andrew). To re-summarize given the new revision, this patch now removes an outdated reference to "most personal computers" having only one CPU, and changes the use of "singleprocessor" and "single processor" in CONFIG_SMP's documentation to "uniprocessor" across all arches where that documentation is present.
