[PATCH] kprobes: fix race in aggregate kprobe registration
When registering multiple kprobes at the same address, we leave a small window where the kprobe hlist will not contain a reference to the registered kprobe, leading to potentially, a system crash if the breakpoint is hit on another processor. Patch below now automically relpace the old kprobe with the new kprobe from the hash list.
