Cover letter [-mm][PATCH 0/6] (yet another) kprobes x86 code unification and boosters

Hello all,

I developed a series of patches which unifies kprobes code on x86
and introduces boosters on x86-64. These patches can be applied to 2.6.24-rc4-mm1.

The purpose of this patchset is unifying kprobes_[32|64].[c|h] to kprobes.[c|h] for simplifying code maintenance.

I know these patches are conflicting with Harvey's patch. We need to solve that.

kprobe-booster and kretprobe-booster were explained in:
http://marc.info/?l=linux-kernel&m=113862526017068&w=2

Currently, these patches do unification as following order.
1. Clean up and fix bugs in kprobes[1/6, 2/6].
2. Introduce kprobe-booster and kretprobe-booster for x86-64[3/6, 4/6]. (x86-32 kprobes already has same functionalities)
3. Prepare unification[5/6].
4. Unify kprobes code[6/6].

If you have any comment, please let me know.

Best Regards,
