Thread-topic: [PATCH] utilization of kprobe_mutex is incorrect on x86_64

 <<kprobe_incorrect_kprobe_mutex_2.6.14-rc2_x86_64.patch>> I found it
when reading the source codes. Basically, the bug could break
kprobe_insn_pages under multi-thread environment. PPC arch also has the
problem.
Here is the patch against x86_64.
