It does not apply to the 4.4.y kernel branch. If you feel it should be
there, please provide a working backport.

If you look closely, not many Spectre-related patches are merged into
4.4.y as no one has taken the time to do the backporting. I thought
someone was working on this, but odds are they just moved to 4.9.y or
4.14.y as everyone really should if they care about these issues with
their platforms.

So if you care about Spectre, I strongly recommend using 4.14.y or
newer.

thanks,
