No, perhaps not all of them. Some of them fixes issues that must
have been introduced recently, so they would qualify for older trees
only if the respective base patches also went there.

That is,
- the domain save one likely is a candidate, but it should see some
  broader testing first
- the pv cpuid masking one likely is a candidate, together with Intel's
  original one (whether just for 4.0 or also for 3.4 is more difficult to
  judge)
- the IRQ signed-ness one should be applicable to 4.0 only
- the MCE, superpage, wrmsr warning, and pyxc ones fall into the
  above category
- the LZO patches, while supposedly safe, don't look like backporting
  candidates to me
