[PATCH 1/2] arm: kprobes: remove kprobe_exceptions_notify

Show all headers | View raw

Commit fc62d0207ae0 ("kprobes: Introduce weak variant of
kprobe_exceptions_notify()") introduces a generic empty version of the
function for architectures that don't need special handling, like arm.
As such, remove the arch/arm/ specific handler.
