commit 1c2c7029 upstream. This patch fixes a complain about possible sleep during spinlock aquired "BUG: sleeping function called from invalid context at include/crypto/algapi.h:426" for the ctr(aes) and ctr(des) s390 specific ciphers. Instead of using a spinlock this patch introduces a mutex which is save to be held in sleeping context. Please note a deadlock is not possible as mutex_trylock() is used. Signed-off-by:
