X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cb6950b7152fb3760942f9cb16bd2a35e5a1bfd1;p=openwrt%2Fstaging%2Fblogic.git

arm64: kprobes: remove kprobe_exceptions_notify

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 arm64.
As such, remove the arch/arm64/ specific handler.
