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 <cai@lca.pw> Message-Id: <20200402153955.1695-1-cai@lca.pw> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
