From 514ccc194971d0649e4e7ec8a9b3a6e33561d7bf Mon Sep 17 00:00:00 2001 From: Qian Cai Date: Thu, 2 Apr 2020 11:39:55 -0400 Subject: [PATCH] x86/kvm: fix a missing-prototypes "vmread_error" The commit 842f4be95899 ("KVM: VMX: Add a trampoline to fix VMREAD error handling") removed the declaration of vmread_error() causes a W=1 build failure with KVM_WERROR=y. Fix it by adding it back. arch/x86/kvm/vmx/vmx.c:359:17: error: no previous prototype for 'vmread_error' [-Werror=missing-prototypes] asmlinkage void vmread_error(unsigned long field, bool fault) ^~~~~~~~~~~~ Signed-off-by: Qian Cai Message-Id: <20200402153955.1695-1-cai@lca.pw> Signed-off-by: Paolo Bonzini --- arch/x86/kvm/vmx/ops.h | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/x86/kvm/vmx/ops.h b/arch/x86/kvm/vmx/ops.h index 09b0937d56b1ee..19717d0a110097 100644 --- a/arch/x86/kvm/vmx/ops.h +++ b/arch/x86/kvm/vmx/ops.h @@ -12,6 +12,7 @@ #define __ex(x) __kvm_handle_fault_on_reboot(x) +asmlinkage void vmread_error(unsigned long field, bool fault); __attribute__((regparm(0))) void vmread_error_trampoline(unsigned long field, bool fault); void vmwrite_error(unsigned long field, unsigned long value);
