Subject: [PATCH 19/21] LoongArch: convert to use arch_cpu_is_hotpluggable()
MIME-Version: 1.0

Message-Id: <E1r5R4B-00Ct0G-Kk@rmk-PC.armlinux.org.uk>
Sender: Russell King <rmk@armlinux.org.uk>
Date:   Tue, 21 Nov 2023 13:45:27 +0000
Precedence: bulk

Convert loongarch to use the arch_cpu_is_hotpluggable() helper rather
than arch_register_cpu(). Also remove the export as nothing should be
using arch_register_cpu() outside of the core kernel/acpi code.
