If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@xxxxxxxxx>
All warnings (new ones prefixed by >>):
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...)?
