I have done some basic tests with the patches on a 2.6.9-30.EL on a Power5 LPAR.
All the basic modules (kprobe, jprobe, retprobe) worked fine. The changes I had
to make to the above patchset were:
- Fixup arch/powerpc/kernel/process.c as the patch generated wouldn't apply on
2.6.9-30.EL
- Add the check:
if (args->regs && user_mode(args->regs))
return ret;
in arch/powerpc/kernel/kprobes.c
