Since the regression was introduced in 5.1, it should be backported
to stable trees.

I only put Fixes: tags on patches that are actually fixing something.
Quoting submitting-patches.rst:

  A Fixes: tag indicates that the patch fixes an issue in a previous
  commit.

Since the preceding two patches are just preparing for the fix, and
not actually fixing an issue in themselves, it seems wrong to add a
Fixes: tag for them.  However, mentioning it in the commit message
for the patch that does fix the issue is probably worth it.  Thanks.
