A rather large change but reading the description it seems to address
quite a few problems. And we know usb serial has not been in its best
state in 2.6.31. Seems one of the things to require an ABI change.

One of the bigger ones, but as it changes the build environment and not the
code itself it would be expected to cause build failures if wrong.

Another one that causes the ABI to bump. All changes to functions to
pass additional information. It does not say much about the reasons but
additionally passing some caller's credentials sounds a bit like security.

When looking through those I did not catch anything bad. I had a
closer look at the three which were bigger than the usual and added
some comments above.

I tweaked the headers a bit (mainly adding a buglink to the common tracking
bug for all of those) and sent the result to my PPA. For the final take I'd
also add Ack lines to them.
I would suggest that at least us in the kernel team, that run karmic add this
to their apt lines. So we might find out ourselves when we break important
things. This maybe needs a bit more rubbing in on UDS as I am not sure how
well mails like this are read.
One more thing, I updated the maint-modify-patch script, as it failed in some
cases, and added it to the maint-tools repo.
