Please read the stable kernel rules for what is, and is not allowed.
Generally a patch that does:
	drivers/tty/n_gsm.c | 410 ++++++++++++++++++++++++++++++--------------
is not allowed.

Please sort by what is stable fixes, and what is not.  Given that you
don't seem to want to backport patches to older stable kernels when they
fail to apply, why are any of these needed in stable kernels if the
older ones are not also going to be merged there?
