Ingo, you could/should probably fold this into Masami's kprobe
unification patch.

The original code had these whitespace, because (I think)
kretprobe_trampoline_holder() had just hold a memory space
for hooking function return. And now, it has actual code.
So the whitespace can be removed.

Thank you.

Hmm, this function still a bit special, because it is not
called directly. kretprobe uses kretprobe_trampoline symbol,
which is defined in this function.
Anyway, I think the whitespace does not help us understand it...

i applied this as a separate patch - better for whitespace changes to 
not be mixed into unification patches.
