With Martin's continuing approval, here is the s390x part of the patch.

This creates compat_sigset_t and compat_old_sigset_t i.e.  just the
types.  This is just the generic part, the architecture specific parts
will be sent to respective maintainers.

The current LOG_BUF size is a bit confusing the first
time that "make oldconfig" is used.  It's difficult to
select anything other than the default value.

Also, you (Linus) expressed a desire to have this
configurable only if DEBUG_KERNEL or "kernel hacking"
was enabled, so I've changed it to accomplish that.

This patch also uses Kconfig in a way that Roman intended
since a patch in 2.5.52 which enables default values if
a prompt is not enabled, but lets values be chosen when
the prompt is enabled.  You also asked for this in setting
this config option.

This provides for separate global and per-thread debug control
register value(s), which are switched as appropriate.  This allows
us to use both an external JTAG debugger for debugging the kernel
as well as using gdb to debug user programs.

This is needed for Open Firmware on older powermacs to be able to
load the wrapper.  Without this OF gives a "CLAIM failed" error.

Some error checking was added ca. 2.5.58 that would remove a device from 
its bus's list of devices if device_attach() returned an error. This 
included errors returned from drv->probe(), and the -ENODEV error returned
if the device wasn't bound to any driver.

This was BAD since it was perfectly fine for a device not to bind to a 
driver immediately, and for drivers to return an error on probe() if the 
device doesn't exactly qualify as one it supports. 

This changes device_attach() and driver_attach() to both return void, 
instead of an error, since they really can never fail hard enough to cause
the device or driver to be removed from the bus. 

probing tells us they already have a range. The old information is
stale.

This fixes svc_tcp_recvfrom().
