[PATCH v2 3/5] lib/cpumask: delete misleading comment

From: Yury Norov
Date: Mon Sep 05 2022 - 19:09:00 EST


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.
