[RFC PATCH v2 17/25] smp, sh: kill SMP single function call interrupt

From: Jiang Liu
Date: Wed Sep 11 2013 - 12:10:27 EST


From: Jiang Liu <jiang.liu@xxxxxxxxxx>

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.
