解决方法：进入arch/arm/kernel/entry-armv.S屏掉这两句话
因为[ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_user
get_irqnr_preamble allows machines to take some action before entering theget_irqnr_and_base loop. On iop we enable cp6 accessarch_ret_to_user is added to the userspace return path to allow individual architectures to take actions, like disabling coprocessor access, before the final return to userspace.Per Nicolas Pitre's note, there is no need to cp_wait on the return to user as the latency to return is sufficient.
