Arduino 101 / ARC: tests/kernel/fifo/fifo_api/ fails after 3d9ba10b5c903265d870a9f24065340d93e7d465

Starting said commit:

    arch: arc: bug fixes and optimization in exception handling
    
    The original exception handling has space to optimize and
    and some bugs need to be fixed.
    
    * define NANO_ESF
       * add the definition of NANO_ESF which is an irq_stack_frame
       * add the corresponding codes in exception entry and handler
       * remove _default_esf
    * implement the _ARCH_EXCEPT
       * use trap exception to raise exception by kernel
       * add corresponding trap exception entry
       * add _do_kernel_oops to handle the exception raised by
         _ARCH_EXCEPT.
    * add the thread context switch in exception return
       * case: kernel oops may raise thread context switch
       * case: some tests will re-implement SysFatalHandler to raise
         thread context switch.
       * as the exception and isr are handled in kernel isr stack, so
         the thread context switch must be in the return of exception/isr
         , and the exception handler must return, should not be decorated
         with FUNC_NORETURN
    * for arc, _is_in_isr should consider the case of exception

the exception loop repeats for ever, the board is stuck there.

Thanks, I can reproduce the problem on EMSK. Looks like a problem was introduced for the irq offload.

fixed.
