From: Ananth N Mavinakayanahalli <ananth@in.ibm.com>
This patch adds CONFIG_HAVE_KRETPROBES to the arch/<arch>/Kconfig file
for relevant architectures with kprobes support. This facilitates easy
handling of in-kernel modules (like samples/kprobes/kretprobe_example.c)
that depend on kretprobes being present in the kernel.
This patch depends on Mathieu Desnoyers' "Instrumentation menu removal"
patchset (http://marc.info/?l=linux-kernel&m=119496432229633&w=2)
Updated to apply on 2.6.24-rc4-mm1. Thanks to Sam Ravnborg for helping
make the patch more lean.
V2: Per Mathieu's suggestion, added CONFIG_KRETPROBES and fixed up
dependencies.
