From mboxrd@z Thu Jan 1 00:00:00 1970 From: dave.martin@linaro.org (Dave Martin) Date: Mon, 28 Jan 2013 17:34:04 +0000 Subject: [RFC PATCH] ARM: Export the CPU logical map to modules Message-ID: <1359394444-16610-1-git-send-email-dave.martin@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org It is reasonable for loadable modules to be CPU topology aware (particular examples include cpufreq and cpuidle drivers). This patch exports __cpu_logical_map, so that modules can use the cpu_logical_map() interface declared in . Signed-off-by: Dave Martin --- If anyone has a strong view on whether this should be EXPORT_SYMBOL_GPL(), I don't have a problem with changing that. I'm not sure of the precise etiquette here. Certainly this does not feel like a very "public" interface. Perhaps we should wrap this in a real function for export to modules, rather than encouraging them to poke the __cpu_logical_map[] array (albeit via a predefined macro). arch/arm/kernel/setup.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/arch/arm/kernel/setup.c b/arch/arm/kernel/setup.c index 3f6cbb2..1b9e5bf 100644 --- a/arch/arm/kernel/setup.c +++ b/arch/arm/kernel/setup.c @@ -428,6 +428,7 @@ void cpu_init(void) } int __cpu_logical_map[NR_CPUS]; +EXPORT_SYMBOL(__cpu_logical_map); void __init smp_setup_processor_id(void) { -- 1.7.4.1
