Splitting it is a very wise idea so that we can have all the -stable kernels patched up with a working single step function.
The separated patches can easily be tagged with the CC line examples as shown below:
Cc: <stable at vger.kernel.org> # 3.15.x-
Cc: <stable at vger.kernel.org> # 4.4
Cc: <stable at vger.kernel.org> # 4.4-4.5
I had dropped the original patch.
