Hi ! Not sure if this is a bug or maybe a placeholder for something... so patch - but maybe someone that knows this code can give it a look. arch/mips/kvm/emulate.c:emulation_result kvm_mips_complete_mmio_load() <snip> 2414 case 2: 2415 if (vcpu->mmio_needed == 2) 2416 *gpr = *(int16_t *) run->mmio.data; 2417 else 2418 *gpr = *(int16_t *) run->mmio.data; 2419 2420 break; <snip> either the if/else is not needed or one of the branches is wrong or it is a place-holder for somethign that did not get done - in which case a few lines explaining this would be nice (e.g. like in arch/sh/kernel/traps_64.c line 59) line numbers refer to 4.1-rc2 thx! hofrat
