Subject: [PATCH] x86/kprobes: Remove trampoline_handler() prototype
... and make it static. It is called only by the kretprobe_trampoline()
from asm.
It was marked __visible so that it is visible outside of the current
compilation unit but that is not needed as it is used only in this
compilation unit.
