Subject: [PATCH v2] irqchip: LoongArch: Select GENERIC_IRQ_EFFECTIVE_AFF_MASK if SMP
Date: Thu, 27 Oct 2022 11:39:09 +0800 [thread overview]
Message-ID: <1666841949-5244-1-git-send-email-yangtiezhu@loongson.cn> (raw)
An IRQ's effective affinity can only be different from its configured
affinity if there are multiple CPUs. Make it clear that this option is
only meaningful when SMP is enabled.
