    38  * This framework allows applications to register to receive a notification
     38 * This framework allows applications to subscribe to receive a notification
    3939 * when interrupt is detected. The application may provide a simple 'top-half'

     44 * - IMETHOD: interface and method as set by the SYS_IPC_IRQ_SUBSCRIBE syscall
    4645 * - ARG1: payload modified by a 'top-half' handler (scratch[1])
