From: Sam Ravnborg Date: Tue, 29 Apr 2008 07:58:51 +0000 (-0700) Subject: cpu: fix section mismatch warning in reference to register_cpu_notifier X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f7b16c108fd044adc422ff21b5d6c16022462fd0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git cpu: fix section mismatch warning in reference to register_cpu_notifier Fix following warnings: WARNING: vmlinux.o(.text+0xc60): Section mismatch in reference from the function kvm_init() to the function .cpuinit.text:register_cpu_notifier() WARNING: vmlinux.o(.text+0x33869a): Section mismatch in reference from the function xfs_icsb_init_counters() to the function .cpuinit.text:register_cpu_notifier() WARNING: vmlinux.o(.text+0x5556a1): Section mismatch in reference from the function acpi_processor_install_hotplug_notify() to the function .cpuinit.text:register_cpu_notifier() WARNING: vmlinux.o(.text+0xfe6b28): Section mismatch in reference from the function cpufreq_register_driver() to the function .cpuinit.text:register_cpu_notifier() register_cpu_notifier() are only really defined when HOTPLUG_CPU is enabled. So references to the function are OK. Annotate it with __ref so we do not get warnings from callers and do not get warnings for the functions/data used by register_cpu_notifier().
