The two are together in the series and fix two different bugs. They do
not need to reference each other.

The first patch fixes a bug introduced in 3.18. There would be no splat
in 3.17 because the check didn't exist then. But the RCU reference
while cpu offline (second bug) was introduced in 3.17 and that is what
the second patch fixes.

We don't need more tags.

I may add that, but more appropriate would be to add the commit that
fixes the bug to the bug report.
