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. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
