In s390 des and 3des ctr mode there is one preallocated page used to speed up the en/decryption. This page is not protected against concurrent usage and thus there is a potential of data corruption with multiple threads. The fix introduces locking/unlocking the ctr page and a slower fallback solution at concurrency situations. Cc: stable@vger.kernel.org Signed-off-by:
