As we execute real mode guests in VM86 mode, exception have to be reinjected appropriately when the guest triggered them. For this purpose the patch adopts the real-mode injection pattern used in vmx_inject_irq to vmx_queue_exception, additionally taking care that the IP is set correctly for #BP exceptions. Furthermore it extends handle_rmode_exception to reinject all those exceptions that can be raised in real mode. This fixes the execution of himem.exe from FreeDOS and also makes its debug.com work properly. Note that guest debugging in real mode is broken now. This has to be fixed by the scheduled debugging infrastructure rework (will be done once base patches for QEMU have been accepted).
