Hi all,

this series of patches has been based and tested on next-20170125 with
CRYPTO_MANAGER_DISABLED_TESTS not set.

The series adds support to the hmac(shaX) algorithms first, then combines
both the Atmel SHA and AES hardware accelerators to implement
authenc(hmac(shaX),Y(aes)) algorithms as used by IPSEC/SSL connections.

It has also been tested with strongswan + xl2tpd to create an IPSEC+L2TP
(transport mode) VPN and strongswan only (tunnel mode) for an IPSEC VPN.

Then iperf was used to measure the bandwidth improvement in tunnel mode:

drivers                                    AES SHA SPLIP iperf half-duplex
                                                         Mbit/s
authenc(hmac(sha1-generic),cbc(aes))        SW   SW  N/A 27.7
authenc(hmac(sha1-generic),atmel-cbc-aes)   HW   SW  N/A 30.2 (mainline)
authenc(atmel-hmac-sha1,atmel-cbc-aes)      HW   HW   no 29.1
atmel-authenc-hmac-sha1-cbc-aes             HW   HW  yes 38.8

SPLIP: Secure Protocol Layers Improved Performances (AES+SHA combined).

Some patches of this series are purely transitional: I've split the
modifications into many patches to ease the review.

All applied.  Thanks.
