Here is a list of things we need to do on s390 for 2.6:

arch/s390/
~~~~~~~~~

o A nastly memory management problem causes random crashes.
These appear to be fixed/hidden by the objrmap patch, more
investigation is needed.

drivers/s390/
~~~~~~~~~~~~~

o Early userspace and 64 bit dev_t will allow the removal of most of
dasd_devmap.c and dasd_genhd.c.

o The 3270 console driver needs to be replaced with a working one
(prototype is there, needs to be finished).

o Minor interface changes are pending in cio/ when the z990 machines
are out.

There are some more things being worked on that are either post-2.6.0
or are likely to remain outside of the official kernel (i.e. not for
your list):

o Jan Glauber is working on a fix for the timer issues related
to running on virtualized CPUs (wall-clock vs. cpu time).

o new zfcp fibre channel driver

o the qeth driver will become GPL soon

o a block device driver for ramdisks shared among virtual
machines

o driver for crypto hardware

o 'claw' network device driver
