Subject: [PATCH] virt: acrn: add hotplug_cpu dependency
Date: Thu, 25 Feb 2021 14:38:30 +0100 [thread overview]
Message-ID: <20210225133838.2196965-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Without CPU hotplug, acrn fails to build:
drivers/virt/acrn/hsm.c:389:3: error: implicit declaration of function 'remove_cpu' [-Werror,-Wimplicit-function-declaration]
remove_cpu(cpu);
^
drivers/virt/acrn/hsm.c:402:2: error: implicit declaration of function 'add_cpu' [-Werror,-Wimplicit-function-declaration]
add_cpu(cpu);
^
Enforce the dependency through Kconfig to avoid the build failure.
Fixes: 666834c47d3b ("virt: acrn: Introduce ACRN HSM basic driver")
