Will Deacon a22d570aee arm64: kprobes: Avoid calling kprobes debug handlers explicitly ... Kprobes bypasses our debug hook registration code so that it doesn't get tangled up with recursive debug exceptions from things like lockdep: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/324385.html However, since then, (a) the hook list has become RCU protected and (b) the kprobes hooks were found not to filter out exceptions from userspace correctly. On top of that, the step handler is invoked directly from single_step_handler(), which *does* use the debug hook list, so it's clearly not the end of the world. For now, have kprobes use the debug hook registration API like everybody else. We can revisit this in the future if this is found to limit coverage significantly.
