From bd09f6061843d5266b0ae7ebc87255bd2ca95a49 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Thu, 5 Dec 2013 00:12:58 +0800 Subject: [PATCH] smp, hexagon: kill SMP single function call interrupt Commit 9a46ad6d6df3b54 "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 intterupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.
