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 <[email protected]> Message-Id: <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>
