If I take these, than 4.19 is vulnerable. So someone upgrading from 4.14 to 4.19 will regress :(
Can you please send me a 4.19 series so I can apply that before this one?

OK, didn't think about that being a problem. Working on it. Pretty sure there's exactly one patch needed for that.
one? All of these except one showed up in 4.20 and were not backported to 4.19 from what I can tell. The last one is in 5.0-rc1 and not even backported to 4.20 either, which means someone messed up and didn't tag it properly with a cc: stable patch :(
My bad, I see now I was looking at v4.20 when I made that comment, not v4.19.
Or they didn't think it was important enough to warrant backporting.
Fair enough, then I have to ask why it's included in this series at all...
I've been backporting all "spectre" branch patches as kept in the linux-arm repo, with the assumption they're all important. If the last patch is not deemed worthy of going into stable now would be a good time to declare it so as I have patch sets for v4.19 and v4.9 stable versions about ready to publish.
Isn't it up to you to determine what is and is not important to get this all working properly? You are testing all of this, right? :)
thanks,
