From 7102b3bb070fdf4580a05cbfc5ad3c0691dc4bf9 Mon Sep 17 00:00:00 2001 From: Yury Norov Date: Mon, 5 Sep 2022 16:08:18 -0700 Subject: [PATCH] lib/cpumask: delete misleading comment The comment says that HOTPLUG config option enables all cpus in cpu_possible_mask up to NR_CPUs. This is wrong. Even if HOTPLUG is enabled, the mask is populated on boot with respect to ACPI/DT records.
