Subject: [RFC PATCH v2 03/25] smp, ARC: kill SMP single function call interrupt
Date: Thu, 12 Sep 2013 00:07:07 +0800 [thread overview]
Message-ID: <1378915649-16395-4-git-send-email-liuj97@gmail.com> (raw)
In-Reply-To: <1378915649-16395-1-git-send-email-liuj97@gmail.com>
From: Jiang Liu <jiang.liu@huawei.com>
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.
