Subject: [PATCH] x86/kvm: Fix -Wmissing-prototypes warnings
Date: Thu, 10 Oct 2019 14:37:25 +0800 [thread overview]
Message-ID: <1570689445-43358-1-git-send-email-wang.yi59@zte.com.cn> (raw)
We get two warning when build kernel with W=1:
arch/x86/kernel/kvm.c:872:6: warning: no previous prototype for ‘arch_haltpoll_enable’ [-Wmissing-prototypes]
arch/x86/kernel/kvm.c:885:6: warning: no previous prototype for ‘arch_haltpoll_disable’ [-Wmissing-prototypes]
Including the missing head file can fix this.
