From b4cd605ca92d9a8a2f71355cb45dd943ebcb0c97 Mon Sep 17 00:00:00 2001 From: "David A. Long" Date: Wed, 5 Mar 2014 21:41:29 -0500 Subject: ARM: Make arch_specific_insn a define for new arch_probes_insn structure Because the common underlying code for ARM kprobes and uprobes needs to share a common architecrure-specific context structure, and because the generic kprobes include file insists on defining this to a dummy structure when kprobes is not configured, a new common structure is required which can exist when uprobes is configured without kprobes. In this case kprobes will define a dummy structure, but without the define aliasing the two structure tags it will not affect uprobes and the shared probes code. Signed-off-by: David A.
