Subject: [RFC PATCH v3 06/19] smp, blackfin: kill SMP single function call interrupt
Date: Thu,  5 Dec 2013 00:12:57 +0800	[thread overview]
Message-ID: <1386173591-28514-7-git-send-email-liuj97@gmail.com> (raw)
In-Reply-To: <1386173591-28514-1-git-send-email-liuj97@gmail.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 intterupt
is needed for architecture specific code to support generic SMP function
call interfaces, so kill the redundant single function call interrupt.
