Martin,

the default target seems to be broken. The old way
("make image modules") works fine. Not that I care too much,
but I got some grief in sparc about it. FYI.

itcev@niphredil linux-2.6.0-test6-s390]$ make CROSS_COMPILE=/q/cross/bin/s390-ibm-linux-gnu-  ARCH=s390
..............
  OBJCOPY arch/s390/boot/image
make[1]: *** No rule to make target `arch/s390/boot/listing'.  Stop.

This is all fine, but the removal of dst_link_failure is missing.
Why is that? We agreed about it several update cycles before.
I am not doing because I'm bored, we hit actual oopses (ok, on 2.4).

My unified sysrq patch is missing.

Also, why is the tub driver not being updated? This is an issue
because passwords are visible on 3215 and there is NO WAY
around it, except TERM CONMODE 3270 and then using tub.
I seem to remember promises about New Super-Duper Improved
and Clean tub, but it's nowhere to be seen, so meanwhile it
should not be too hard to keep old tub operating. You don't
even have to do anything. Just use your maintainer powers to
refuse "cleaups" like the devstat removal unless they fix all
in-tree drivers for related breakage. Then contributors will
have to fix it.

Just "make" works fine for me. And there isn't another patch
in the pipe for the s390 Makefiles. In my Makefiles there isn't
a "listing" target anymore.

This is one of the cases of "If you don't do it yourself, nobody will".
I am no expert in regard to network drivers but I'll check in your
patch now. Fritz seems to be too busy to do it himself.

Hi Linus,
more patches for s390. 7 this time, one is big and another one is VERY big.
Heiko spent an awful lot of time on porting the zfcp scsi host adapter to
2.6. He is finished with it, the rest is bug fixing. The patch is 14000
lines, so I better not sent this to lkml.

Short descriptions:
1) Base fixes for s390.
2) Common i/o layer fixes. One of the things included is the removal of
   the hack in ccwgroup.c which Christoph Hellwig complained about.
3) dasd driver update. We removed the dynamic major allocation code and
   replaced devnos with busids. We definitly like 20 bit minors :-)
4) Kerner janitors complained about verify_area in the ctc driver.
5) iucv patch. The driver core complained about iucv not having a release
   function. Add one.
6) qeth bug fixes and cleanup. Conny removed the read, write and device
   device pointers from the card structure. Unluckily this touches all
   debug statements which produces a rather big patch.

7) The zfcp host adapter.

blue skies,
  Martin.
