Latest 2.6.35 git - 2.6.35-git6 (cd816a0d8...) fails to build
on a s390 box with following error :
drivers/s390/scsi/zfcp_erp.c: In function 'zfcp_erp_thread':
drivers/s390/scsi/zfcp_erp.c:1337: warning: frame size of 'zfcp_erp_thread' is 280 bytes
drivers/s390/scsi/zfcp_qdio.c: In function 'zfcp_qdio_siosl':
drivers/s390/scsi/zfcp_qdio.c:467: error: implicit declaration of function 'ccw_device_siosl'
make[2]: *** [drivers/s390/scsi/zfcp_qdio.o] Error 1
This problem seem to have been introduced with git2 (3cfc2c42c1c...) via
commit 339f4f4eab80caa6cf0d39fb057ad6ddb84ba91e
[SCSI] zfcp: Trigger logging in the FCP channel on qdio error conditions
Thanks

The zfcp commit calls a function that is introduced with
"[S390] cio: CHSC SIOSL Support"
http://148.100.100.18/cgi-bin/gitweb.cgi?p=linux-2.6.git;a=commit;h=c40306ed03b25a71e8a6cb7162e970d9a29c4242
This patch should be part of the s390 patches for the 2.6.36 merge
window. To build the kernel now, either remove the zfcp patch or apply
the cio patch.
