    xtensa: make fake NMI configurable · e4629194
    Max Filippov 提交于
    Do not always use fake NMI when safe, provide Kconfig option instead.
    Print a warning if fake NMI is chosen in unsafe configuration, but allow
    it, because it may work if the user knows that interrupts with
    priorities at or above PMM IRQ are not used. Add a check to NMI handler
    that BUGs if any of these IRQs fire.
