Digging further this seems to be due to stop_cpu().

Shouldn't stop_cpu() be using raw_smp_processor_id()?

Looks to me like your kernel was compiled with !CONFIG_SMP when you triggered
the warnung. Your patch however touches code that gets only compiled with
CONFIG_SMP enabled and it shouldn't be necessary.
I was unabled to reproduce this with Linus' git tree of today. Could you
try that one and send your kernel config?
Please ignore any alloc_bootmem() warnings you might see and also don't run
it with more than 2GB.

Thanks.
Hi Heiko,

With the current linus tree (git 10), kprobe breaks. Even smoke tests are failed in s390x box.
With 2.6.30, the same warning is raised even with CONFIG_SMP enabled. I have pasted the config file used.
