From 0e28bf93a273cce0db67a17428697abb722c36b8 Mon Sep 17 00:00:00 2001 From: Anna-Maria Gleixner Date: Mon, 2 May 2016 11:02:51 +0200 Subject: [PATCH] net: mvneta: Remove superfluous SMP function call Since commit 3b9d6da67e11 ("cpu/hotplug: Fix rollback during error-out in __cpu_disable()") it is ensured that callbacks of CPU_ONLINE and CPU_DOWN_PREPARE are processed on the hotplugged CPU. Due to this SMP function calls are no longer required. Replace smp_call_function_single() with a direct call to mvneta_percpu_enable() or mvneta_percpu_disable(). The functions do not require to be called with interrupts disabled, therefore the smp_call_function_single() calling convention is not preserved.
