工具/软件：Linux
加密框架中存在问题，如下所示：
(1)环境：
Linux3.2，AM335x，硬件加密卡（使用 SM1和 SM3），与 SPI 通信
(__LW_AT__2）问题：
在加密帧 中，必须直接使用 spidev_sync_write 和 spidev_sync_read，这 将产生 oops->bug:原子调度
我 已经解决 了乒乓方向，混凝土是：
crypto_CBC_decrype->blkciphip_walk virt->blkciphip_walk first->blkciphip_Walk next -> blkciphip_next 快速->blkciphip_map_src->scatterwalk 地图->crypto kmap_atic -> kmap_atter_atic -> kmap_atomic
kmap_atomic --> kmap--> kmap--> >确定！
但 仍是 Ping in Direction，Oops 为：Ω
