[RFC]kprobes functionality with kernel-hacking disabled

[He Kuang]

kprobes is so excellent in performance analysis. But in many practical 
performance analysis scenarios, performance & debuging related configs
maybe disabled. So, we should recompile the kernel for further analysis,
this is not so convinient.

I've read this thread asked a question to use kprobes as a module
(https://lkml.org/lkml/2012/5/15/46), and know the ftrace dependence
 issue. But when we meet a kernel compiled without CONFIG_KPROBES*, 
the only thing we need is the basic kprobes funtionality, have ftrace 
or not is not the major problem, in fact, most cases ftrace is disabled
too.

Do you have any advices on the conflicts between kernel hacking tools and 
practical kernel which compiled without it? If there is no kprobes 
module, what should we use?
