I test the patch in IA32 and IA64 platfrom about RHEL4-U3-RC3 2.6.9-34 kernel
version, and in IA32 there is one patch need modification in nx.patch
+void __kprobes arch_remove_kprobe(struct kprobe *p)
should be +void arch_remove_kprobe(struct kprobe *p),
__kprobes is not defined in RHEL4 series.
And in IA64 platform, http://sourceware.org/bugzilla/show_bug.cgi?id=2071 still
unsolved.
And I will test in x86_64 platform.
And as anath pointed out, in iA64 platform it also should be checked.
if (args->regs && user_mode(args->regs))
return ret;
Now I am sure for IA32, x86_64, for safety I suggest it should be check in all
platform.
