crypto: bcm - Verify GCM/CCM key length in setkey
The setkey function for GCM/CCM algorithms didn't verify the key
length before copying the key and subtracting the salt length.
This patch delays the copying of the key til after the verification
has been done. It also adds checks on the key length to ensure
that it's at least as long as the salt.

crypto: xor - use ktime for template benchmarking
Currently, we use the jiffies counter as a time source, by staring at
it until a HZ period elapses, and then staring at it again and perform
as many XOR operations as we can at the same time until another HZ
period elapses, so that we can calculate the throughput. This takes
longer than necessary, and depends on HZ, which is undesirable, since
HZ is system dependent.
Let's use the ktime interface instead, and use it to time a fixed
number of XOR operations, which can be done much faster, and makes
the time spent depend on the performance level of the system itself,
which is much more reasonable. To ensure that we have the resolution
we need even on systems with 32 kHz time sources, while not spending too
much time in the benchmark on a slow CPU, let's switch to 3 attempts of
800 repetitions each: that way, we will only misidentify algorithms that
perform within 10% of each other as the fastest if they are faster than
10 GB/s to begin with, which is not expected to occur on systems with
such coarse clocks.

crypto: lib/chacha20poly1305 - Set SG_MITER_ATOMIC unconditionally
There is no reason for the chacha20poly1305 SG miter code to use
kmap instead of kmap_atomic as the critical section doesn't sleep
anyway. So we can simply get rid of the preemptible check and
set SG_MITER_ATOMIC unconditionally.
Even if we need to reenable preemption to lower latency we should
be doing that by interrupting the SG miter walk rather than using
kmap.

crypto: inside-secure - Reuse code in safexcel_hmac_alg_setkey
The code in the current implementation of safexcel_hmac_alg_setkey
can be reused by safexcel_cipher. This patch does just that by
renaming the previous safexcel_hmac_setkey to __safexcel_hmac_setkey.
The now-shared safexcel_hmac_alg_setkey becomes safexcel_hmac_setkey
and a new safexcel_hmac_alg_setkey has been added for use by ahash
transforms.
As a result safexcel_aead_setkey's stack frame has been reduced by
about half in size, or about 512 bytes.

crypto: Kconfig - mark unused ciphers as obsolete
We have a few interesting pieces in our cipher museum, which are never
used internally, and were only ever provided as generic C implementations.
Unfortunately, we cannot simply remove this code, as we cannot be sure
that it is not being used via the AF_ALG socket API, however unlikely.
So let's mark the Anubis, Khazad, SEED and TEA algorithms as obsolete,
which means they can only be enabled in the build if the socket API is
enabled in the first place.
