From 614aab527b3d48f481854c215251471407473599 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 16 Dec 2013 00:36:25 +0800 Subject: smp, alpha: 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 interrupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.
