There is a fast-path of MMIO emulation inside hyp mode. The handling of single-step is broadly the same as kvm_arm_handle_step_debug() except we just setup ESR/HSR so handle_exit() does the correct thing as we exit. For the case of an emulated illegal access causing an SError we will exit via the ARM_EXCEPTION_EL1_SERROR path in handle_exit(). We behave as we would during a real SError and clear the DBG_SPSR_SS bit for the emulated instruction.
