If the git commit has the "cc: stable@" marking in it, yes, it will be
picked up.  Without the actual git ids, it's hard to know what did, and
what did not, get backported :)

Note, "LTSI" and "LTS" are two different things.  "LTSI" is a project
run by some LF member companies, and "LTS" are the normal long term
kernels that I release on kernel.org.  They have vastly different
requirements for inclusion in them.

If you have questions about LTSI, I recommend go asking on their mailing
list.

As for showing up in the 4.14 "LTS" kernel, again, I need git commit ids
to know for sure.

Also, as these are now in Linus's tree, you should be able to look at
the stable releases yourself to see if they are present there, right?
