From bc654671a4524f11d383f1918197cc91fd9642cd Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 24 Jul 2020 11:41:56 -0700 Subject: [PATCH] irqchip/irq-bcm7038-l1: Guard uses of cpu_logical_map [ Upstream commit 9808357ff2e5bfe1e0dcafef5e78cc5b617a7078 ] cpu_logical_map is only defined for CONFIG_SMP builds, when we are in an UP configuration, the boot CPU is 0.
