//Kernel stack space definition in application data space.
//Not that, user can also space a special area in memory for kernel stack space.
//It's strongly recommended that use the internal memory as the kernel stack space if
//there is some internal memory space in target processor.because the internal memory
//has faster access rate than that of the extenal memory space. this can increase the
//efficiency of the e-kernel.
