compile 2.6.23 for zx2000?

compile 2.6.23 for zx2000?

[Grant Grundler]

Hi folks,
After a long break, I'm trying to update the kernel on my ia64 HP zx2000.
Config file is attached. Two issues with kernel.org 2.6.23:

1) Can't build with NUMA=n and DISCONTIG=y.
   Build quickly dies with NODE_DATA being undefined.
   I tried to "work around" it with two changes:
   a) include <asm/nodedata.h> from asm/mmzone.h. Not the other way around!
   No one includes asm/nodedata.h (except processor.h).
   Everyone includes linux/mmzone.h (which includes asm/mmzone.h).
   That needs to include nodedata.h to provide NODE_DATA.
   The few arches I checked define NODE_DATA in their asm/mmzone.h.

   b) added defined(CONFIG_NEED_MULTIPLE_NODES) to a few places that
   check CONFIG_NUMA so NODE_DATA would get properly defined.
   e.g. asm/processor.h for
#if defined(CONFIG_NUMA) || defined(CONFIG_NEED_MULTIPLE_NODES)
        struct ia64_node_data *node_data;
#endif


   I decided this wasn't meant to be when node_cpuid was not defined.
   Forcing CONFIG_NUMA when DISCONTIG was enabled got me alot further:

2) But I'm getting this error:
  CC [M]  drivers/char/ipmi/ipmi_si_intf.o
drivers/char/ipmi/ipmi_si_intf.c:1095: error: __param_hotmod causes a section type conflict
make[3]: *** [drivers/char/ipmi/ipmi_si_intf.o] Error 1

I've no idea what's going on here. config file is attached.

Lastly, I've failed to boot with a 2.6.22-2-mckinley on my zx2000.
But I suspect it's failing because I don't have "noasync" and will
retry with that. (This zx2000 has u320 SCSI card for it's internal disks.)

thanks,

This is probably the same as

Yup - looks like the same symptom at least.
Does Debian have a gcc 4.2 or later compiler with that fixed?

I'd be happy to test it by building/running a 2.6.23 kernel if
given a .deb to install.

thanks,
