From 16436f70abeebb29cd99444e27b310755806c1fa Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Sat, 22 Jan 2022 16:16:14 +0100 Subject: [PATCH] irqchip/gic-v3-its: Fix build for !SMP Commit 835f442fdbce ("irqchip/gic-v3-its: Limit memreserve cpuhp state lifetime") added a reference to cpus_booted_once_mask, which does not exist on !SMP builds, breaking the build for such configurations. Given the intent of the check, short circuit it to always pass.
