>From f80d3cc85327ba84748646bb44a0c45103ef66bc Mon Sep 17 00:00:00 2001 From: Tony Lindgren <[email protected]> Date: Wed, 1 Sep 2010 20:40:47 -0700 Subject: [PATCH 4/6] ARM: Do not call test_for_ipi or test_for_ltrirq on UP systems
Do not call test_for_ipi or test_for_ltrirq on UP systems. Note that we can't put test_for_ltriq into SMP statement as it's inlined into the code and the remaining lines of the macro would still run before UP macro line.
