crypto: caam - use len instead of nents for bulding HW S/G table Currently, conversion of SW S/G table into HW S/G layout relies on nents returned by sg_nents_for_len(sg, len). However this leaves the possibility of HW S/G referencing more data then needed: since buffer length in HW S/G entries is filled using sg_dma_len(sg), the last entry in HW S/G table might have a length that is bigger than needed for the crypto request. This way of S/G table conversion is fine, unless after converting a table more entries have to be appended to the HW S/G table. In this case, crypto engine would access data from the S/G entry having the incorrect length, instead of advancing in the S/G table. This situation doesn't exist, but the upcoming implementation of IV update for skcipher algorithms needs to add a S/G entry after req->dst S/G (corresponding to output IV).

crypto: caam/qi - add ablkcipher and authenc algorithms Add support to submit ablkcipher and authenc algorithms via the QI backend: -ablkcipher: cbc({aes,des,des3_ede}) ctr(aes), rfc3686(ctr(aes)) xts(aes) -authenc: authenc(hmac(md5),cbc({aes,des,des3_ede})) authenc(hmac(sha*),cbc({aes,des,des3_ede})) caam/qi being a new driver, let's wait some time to settle down without interfering with existing caam/jr driver. Accordingly, for now all caam/qi algorithms (caamalg_qi module) are marked to be of lower priority than caam/jr ones (caamalg module).
