From b0db321ba14daca748d5c8ca89298fdb637f9ba8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 13 Feb 2013 22:49:04 +0100 Subject: ARM: prima2: fix __init section for cpu hotplug The code in arch/arm/mach-prima2/headsmp.S is used for both boot time initialization and for cpu hotplug, so it must not be discarded after the initial boot is complete. This replaces the __INIT annotation with __CPUINIT, and marks the sirfsoc_cpu_die as __ref to annotate that it correctly uses the sections. Without this patch, building prima2_defconfig results in: WARNING: arch/arm/mach-prima2/built-in.o(.cpuinit.text+0x130): Section mismatch in reference from the function sirfsoc_boot_secondary() to the function .init.text:sirfsoc_secondary_startup() The function __cpuinit sirfsoc_boot_secondary() references a function __init sirfsoc_secondary_startup(). If sirfsoc_secondary_startup is only used by sirfsoc_boot_secondary then annotate sirfsoc_secondary_startup with a matching annotation.
