From 1d61cf121d7d9085145553294307e81c25586288 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Thu, 5 Dec 2013 00:13:01 +0800 Subject: [PATCH] smp, metag: kill SMP single function call interrupt Commit 9a46ad6d6df3 "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one interrupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.
