Cobal on Linux Again
Does anyone out there have any stories about Acucobol-GT, this is a tool that someone in my organization is sugesting we use as a way to move Cobal off the expensive z/OS LPAR and unto Linux for z/series, runing on an IFL. I am all for it if it works but I would rather not end up with egg on my face if I can help it. - This message and its attachments may contain privileged and confidential information.

Patch 3 of 3 to the UTS Global Cisco CLAW driver
This patch fixes 64-bit bugs in c7000.c so the driver will work for
both 31-bit and 64-bit kernels. This is the third of three patches.
Marcelo, please apply this patch.

Here are three patches to drivers/s390/net/c7000.c, the UTS Global Cisco CLAW driver, in three separate subsequent emails. The first patch fixes a bug where packets can be lost under heavy workload. The second patch removes old kernel-version ifdefs and adds standard GPL license text. The third patch fixes 64-bit bugs so the driver will work for both 31-bit and 64-bit kernels. The patches should apply cleanly to any kernel 2.4.22 or more recent. Marcelo, please apply the patches. Thanks.

Patches for 64-bit 3270 fullscreen operation
Here are two patches that allow operation of ned, the (31-bit) UTS Global full-screen 3270 editor, on 64-bit zSeries machines. Each patch changes arch/s390x/kernel/ioctl32.c to enable processing of the 3270 ioctl commands. The first patch was developed on the Red Hat 2.4.21-15.EL kernel but should work with offsets on all other recent 2.4 kernels. RedHat, please apply this patch. The second patch was developed on Marcelo's 2.4.27-rc5 kernel. Marcelo, please apply this patch. For other 2.4 kernen versions, one or the other patch will probably apply with only offsets; in any case, interpolation should be easy.

I suppose the main point is that stuff like klibc it is better to keep the existing obvious implementation of sys/times.h instead of changing it to a less obvious one. Right now, all non linux specific klibc/include/sys/foo.h files start with #include , which just makes sense.

The times man pages says that the struct tms is defined in sys/times.h.
This doesn't make it necessary to have a linux/times.h header file.
These are kernel headers and not user space headers. Does anybody think
it's important to keep the user/kernel header files names similar ?

Well, the #ifndef can just be removed for most of the architectures
because they are non-smp architectures anyway. But to avoid breaking
anything I decided to play safe and move the whole #ifndef block.
It's up to the arch maintainer to remove the #ifndef if the arch
doesn't need it.
The reason for moving the #ifndef is twofold. 1) it's just confusing
that a common code function depends on CONFIG_SMP in the way do_timer
does. do_timer should do just one thing, and not two but only if this
is a non-smp kernel. 2) do_timer and update_process_times needs to get
separated to make it possible to account cputime independent of the
xtime updates.
