Tool/software: Linux
There is a problem in the crypto framework,The following:
(1)The environment：
linux3.2，am335x，Hardware encryption card（use sm1 and sm3），Communication with spi
（2）The problem:
in the frame of the crypto must used directly spidev_sync_write and spidev_sync_read，this Will produce OOPS-->BUG: scheduling while atomic
and I have already solved the Ping out direction，The concrete is ：
crypto_cbc_decrypt->blkcipher_walk_virt->blkcipher_walk_first->blkcipher_walk_next->blkcipher_next_fast->blkcipher_map_src->scatterwalk_map->crypto_kmap->kmap_atomic ->__kmap_atomic
kmap_atomic --->>kmap------> OK！
but still the Ping in direction，the OOPS is：
