crypto: msm: Add support for FIPS complience

FIPS140-2 certification asks to do a Power on Known Answer tests on each
algorithm which is getting certified. This patch implements the self tests
and hardcoded test vectors.  Also, we need to verify the integrity of
kernel as soon as it boots up. This patch also adds an ioctl for
integrity test along with ioctl to query FIPS status (pass / fail) from
user land.
also, The piece of code is added for FIPS compliance DRBG under
drivers/char/hw_random
This change is already merged to KK mainline.

net/l2tp: don't fall back on UDP [get|set]sockopt

The l2tp [get|set]sockopt() code has fallen back to the UDP functions
for socket option levels != SOL_PPPOL2TP since day one, but that has
never actually worked, since the l2tp socket isn't an inet socket.

As David Miller points out:

  "If we wanted this to work, it'd have to look up the tunnel and then
   use tunnel->sk, but I wonder how useful that would be"

Since this can never have worked so nobody could possibly have depended
on that functionality, just remove the broken code and return -EINVAL.

net: guard tcp_set_keepalive() to tcp sockets

Its possible to use RAW sockets to get a crash in
tcp_set_keepalive() / sk_reset_timer()

Fix is to make sure socket is a SOCK_STREAM one.
