From 6c81c32f9616fd6f2795dceae2f70943cb4d8609 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Wed, 6 Feb 2008 01:37:51 -0800 Subject: calibrate_delay() must be __cpuinit calibrate_delay() must be __cpuinit, not __{dev,}init. I've verified that this is correct for all users. While doing the latter, I also did the following cleanups: - remove pointless additional prototypes in C files - ensure all users #include This fixes the following section mismatches with CONFIG_HOTPLUG=n, CONFIG_HOTPLUG_CPU=y: WARNING: vmlinux.o(.text+0x1128d): Section mismatch: reference to .init.text.1:calibrate_delay (between 'check_cx686_slop' and 'set_cx86_reorder') WARNING: vmlinux.o(.text+0x25102): Section mismatch: reference to .init.text.1:calibrate_delay (between 'smp_callin' and 'cpu_coregroup_map') Signed-off-by: Adrian Bunk Cc: Ivan Kokshaysky Cc: Richard Henderson Cc: "Luck, Tony" Cc: Ralf Baechle Cc: Paul Mackerras Cc: Benjamin Herrenschmidt Cc: "David S.
