Subject: [PATCH v7 14/15] ARM: Make arch_specific_insn a define for new arch_probes_insn structure
From: "David A. Long" <dave.long@...aro.org>
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.
