arch/arm64/kvm/hyp/nvhe/switch.c:244:28: warning: no previous prototype for function 'hyp_panic' [-Wmissing-prototypes]void __hyp_text __noreturn hyp_panic(struct kvm_cpu_context *host_ctxt)I really wish we could turn these warnings off. They don't add much. Or is there an annotation we could stick on the function (something like __called_from_asm_please_leave_me_alone springs to mind...)?
We should define 'asmlinkage' to whatever makes this warning go away. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
