kprobes performance on i386 vs x86_64

[Keshavamurthy, Anil S]

Possible. Can you rerun the same tests again with some dummy
post-kprobe-handler as djprobes will not come into effect if you have
post-kprobe-handler.

Is there a reason why i386 kprobes are 2-3 times faster than x86_64 on
2.6.19? This is on the same hardware. Is djprobes only working on i386
or something?
