From 9edddaa200df18e08fe0cf21036e8ae467b1363c Mon Sep 17 00:00:00 2001 From: Ananth N Mavinakayanahalli Date: Tue, 4 Mar 2008 14:28:37 -0800 Subject: Kprobes: indicate kretprobe support in Kconfig Add CONFIG_HAVE_KRETPROBES to the 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. Thanks to Sam Ravnborg for helping make the patch more lean. Per Mathieu's suggestion, added CONFIG_KRETPROBES and fixed up dependencies.

IPL from NSS didn't work because the memory detection routine omits any memory sections with a size lower than what MAX_ORDER defines. This causes the detection routine to skip the first memory segment which has a size of 1MB. Which later on will let the kernel think that there is no memory available at all. Since in addition the z/VM memory increment size is 1MB force MAX_ORDER to be 9, so we can support 1MB segments.
