From d6444094042b4f4b4623dc1a2437f61309b9b34b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 24 Sep 2020 16:37:37 +0200 Subject: m68k: split heartbeat out of timer function The heartbeat functionality is mostly separate from the actual timer interrupt handling, and it is only used on five platforms. Split it out into a separate function and call that directly from the timer irq on those platforms.
