From f2a082711905312dc7b6675e913fee0c4689f7ae Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Thu, 15 Jan 2009 09:19:32 -0800 Subject: [PATCH] x86: fix build warning when CONFIG_NUMA not defined. Impact: fix build warning The macro cpu_to_node did not reference it's argument, and instead simply returned a 0. This causes a "unused variable" warning if it's the only reference in a function (show_cache_disable). Replace it with the more correct inline function.
