From 52459ab91363343af8ae252766e9da762344a2e7 Mon Sep 17 00:00:00 2001 From: Leonardo Potenza Date: Sun, 16 Aug 2009 18:55:48 +0200 Subject: [PATCH] x86: Annotate section mismatch warnings in kernel/apic/x2apic_uv_x.c The function uv_acpi_madt_oem_check() has been marked __init, the struct apic_x2apic_uv_x has been marked __refdata. The aim is to address the following section mismatch messages: WARNING: arch/x86/kernel/apic/built-in.o(.data+0x1368): Section mismatch in reference from the variable apic_x2apic_uv_x to the function .cpuinit.text:uv_wakeup_secondary() The variable apic_x2apic_uv_x references the function __cpuinit uv_wakeup_secondary() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: arch/x86/kernel/built-in.o(.data+0x68e8): Section mismatch in reference from the variable apic_x2apic_uv_x to the function .cpuinit.text:uv_wakeup_secondary() The variable apic_x2apic_uv_x references the function __cpuinit uv_wakeup_secondary() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: arch/x86/built-in.o(.text+0x7b36f): Section mismatch in reference from the function uv_acpi_madt_oem_check() to the function .init.text:early_ioremap() The function uv_acpi_madt_oem_check() references the function __init early_ioremap(). This is often because uv_acpi_madt_oem_check lacks a __init annotation or the annotation of early_ioremap is wrong.
