From 7b38493501b76e56f481925ed74ee5ca0f4c6183 Mon Sep 17 00:00:00 2001 From: Satyam Sharma Date: Wed, 17 Oct 2007 18:04:35 +0200 Subject: x86: intel_cacheinfo misc section annotation fixes cache_shared_cpu_map_setup() and cache_remove_shared_cpu_map() are functions called from another function that is __cpuinit. But the !CONFIG_SMP empty-body stubs of these functions are unconditionally marked __init, which is actively wrong, and will lead to oops. But we never saw this oops, because they always managed to get inlined in their callsites, by virtue of being empty-body stubs! They should still be __cpuinit, of course. assocs[], levels[] and types[] are only referenced from function that is __cpuinit. So these are candidates for being marked __cpuinitdata.
