Given that all the 32-bit ARM Spectre patches are sequential in a
branch, it shouldn't be too difficult as it's possible to list all
the commit IDs using:

$ git rev-list v4.16..383fb3ee8024

where 383fb3ee8024 is the current head.  I'm not anticipating at this
time anything further.

Yes, as I mentioned, this is work that David Long is undertaking,
with a separate review process before submitting the backported
patches for inclusion in the appropriate stable tree.
