[Fault-injection-developer] Remove kprobes dependency of kprobes?

[Louis Z. <lou...@li...>]

Dear all,
	I found the current linux kernel had changed debug exception from trap
gate to interrupt gate. It is the only reason that KMMIO depends on
Kprobes. Pls take a look at following dependency diagrams:

Original dependency [2.5.44, 2.5.59]
	2.5<--- KIRQ
	     |
	     |- Kprobes<--- KMMIO<- Page Fault Interceptor
			 |
			 |- DBP Interceptor
			 |
			 |- DR Interceptor

Current dependency [2.5.60, future)
	2.5<--- KIRQ
	     |
	     |- KMMIO<--- Page Fault Interceptor
	     |
	     |- Kprobes<--- DBP Interceptor
			 |
			 |- DR Interceptor

So my questions are, 
1. Should we remove Kprobes and DBP/DR from our FITH tree and change
KMMIO against 2.5.60?
2. Should we port Kprobes to 2.5.60 or wait Kprobes team to do it? 
3. When/How should we make DBP/DR back?
