Drawing ancestry graph would help visualizing what you want to
achieve. You have:
v2.6.15
---o
\
\
\
o---o---o v2.6.15.6
\
x---x---x v2.6.15.6-matt
where x---x---x are your own changes, and you want:
v2.6.15 v2.6.16
---o---o---o---...---o---o
\ \
\ y---y---y 2.6.16-matt
\
o---o---o v2.6.15.6
\
x---x---x 2.6.15.6-matt
to happen, where y---y---y are analogous to x---x---x.
Assuming your branches are:
origin - v2.6.15.6 (from stable team)
master - your changes (2.6.15.6-matt)
you could:
$ git fetch git://../torvalds/linux-2.6.git tag v2.6.16
$ git checkout -b 2.6.16-matt v2.6.16
$ git format-patch origin master | git am -3
Alternatively, you might want to do a real merge:
v2.6.15 v2.6.16
---o---o---o---...---o---o
\ \
\ \
\ m 2.6.16-matt
o---o---o v2.6.15.6 /
\ /
x---x---x 2.6.15.6-matt
Presumably the stable team backported safer changes from the
history between v2.6.15-v2.6.16, and the way things are fixed
are probably quite different from the equivalent fixes in the
development track that led to v2.6.16 (because what's being
patched has also changed), so it is very likely you would see
serious conflicts during this merge. If you do not understand
what the stable team did in order to reimplement certain fixes,
you would have a very difficult time deciding on how to resolve
conflicts with this merge.
At that point it would not be a git question but the kernel
question I am not qualified to answer ;-), but it might be an
interesting exercise.
