I've removed a reference to "most personal computers" being singleprocessor
machines in multiple arches' config help, and also brought the arch/arm spacing
for "singleprocessor" (vs. "single processor" used there originally) in line
with other arches that had that text.
The diff is included below, and cleanly applies and builds on my system. I have
not tested on other systems yet since a documentation fix shouldn't fail to
build inconsistently, but if that's no excuse, I'll be happy to test further
when I can.

* [PATCH] Slightly outdated CONFIG_SMP documentation fix

I've removed a reference to "most personal computers" being singleprocessor
machines in multiple arches' config help, and also brought the arch/arm spacing
for "singleprocessor" (vs. "single processor" used there originally) in line
with other arches that had that text.
The diff is included below, and cleanly applies and builds on my system. I have
not tested on other systems yet since a documentation fix shouldn't fail to
build inconsistently, but if that's no excuse, I'll be happy to test further
when I can.

Either is OK. I tend to prefer continuation-of-this, mainly because it
prevents people from forgetting to cc people who were involved in
earlier discussion.
(Of course, if the discussion graph was complex, no reply-to-all will
capture all participants. Nobody bothers to go through the discussion
gathering the names of all participants so I often end up doing this
when putting the final patch together)

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To re-summarize given the new revision, this patch now removes an outdated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.

I've removed a reference to "most personal computers" being singleprocessor
machines in multiple arches' config help, and also brought the arch/arm spacing
for "singleprocessor" (vs. "single processor" used there originally) in line
with other arches that had that text.
The diff is included below, and cleanly applies and builds on my system. I have
not tested on other systems yet since a documentation fix shouldn't fail to
build inconsistently, but if that's no excuse, I'll be happy to test further
when I can.

I've removed a reference to "most personal computers" being singleprocessor
machines in multiple arches' config help, and also brought the arch/arm spacing
for "singleprocessor" (vs. "single processor" used there originally) in line
with other arches that had that text.
The diff is included below, and cleanly applies and builds on my system. I have
not tested on other systems yet since a documentation fix shouldn't fail to
build inconsistently, but if that's no excuse, I'll be happy to test further
when I can.

I've removed a reference to "most personal computers" being singleprocessor
machines in multiple arches' config help, and also brought the arch/arm spacing
for "singleprocessor" (vs. "single processor" used there originally) in line
with other arches that had that text.
The diff is included below, and cleanly applies and builds on my system. I have
not tested on other systems yet since a documentation fix shouldn't fail to
build inconsistently, but if that's no excuse, I'll be happy to test further
when I can.
