The patch overview:
01: Kconfig and defconfig again. New options: DEBUG_KERNEL, DEBUG_SLAB,
KALLSYMS and DEBUG_SPINLOCK_SLEEP.
02: gcc 3.3 allocates variables that are initialized to zero to the .bss
section instead of .data. This caused some mischief with memory_size
that is detected and stored before .bss is cleared.
03: Add s390 elf relocations to include/linux/elf.h
04: Suppress kern info message about debug levels if DEBUG is off. This
removes quite a lot of unnecessary noise in the boot messages.
05: Adapt s390 backend to changed do_fork call.
06: Add missing include in ptrace.c
07: Documentation changes for the s390 debugging guide.
08: Remove channel device layer.
09: This is the big one: the reworked common i/o layer. I can't see a way
to split this into meaningful parts. It is basically: delete the old
code, add the new code.
10: Add the ccwgroup driver. This is the replacement for chandev and is
surprisingly simple. Grouping is done by echoing a string containing
the subchannels identifiers of a group to an entry in the sysfs.
E.g. for lcs "echo 0:0100,0:0101 > /sysfs/bus/ccwgroup/drivers/lcs/group".
This creates a ccw group with the first subchannel as group leader. The
lcs driver then creates additional attributes in
/sysfs/bus/ccw/devices/0:0100 that are used to configure the lcs device.
Same method is used for ctc but with different attributes. The burden
to find the subchannels which belong to a device is put into the
userspace where it belongs (configure scripts).
11: Update for the documentation about the common io layer.
12: 3215 adaptions for the new channel subsystem interface.
13: sysfs changes for the iucv driver.
14: dasd changes related to the new channel subsystem driver.
15: The rewritten tape device driver.
16: Add cu3088 metadriver. ctc and lcs both use the cu type 3088. To support
these two in the new driver model a metadriver for 3088 subchannels
is introduced. ctc and lcs plug into it to get their subchannels. The
3088 driver just gets all 3088 subchannels for safe-keeping until
ctc or lcs will pick their channels at the time the ccwgroup is created.
17: Convert ctc to the new channel subsystem and 3088 driver.
18: Complete rewrite of the lcs driver. It now uses the new channel subsystem
interface and the 3088 driver. It shrunk a lot and is imho now much
easier to read and understand.
19: Some improvements for the rewritten sclp driver I sent last time.
Most of them are concerned about error recovery.
I keep the finger crossed that everythings applies on the bitkeeper tree.

P.S. some of the patches are too big for lkm. I only post the description
file on lkm. If anybody needs the patches just send me a mail and I'll
forward them.
