Instead of using a homegrown macrofied version of the adr instruction that sets the Thumb bit in the output value, only to ensure that any bx instructions consuming that value will not switch out of Thumb mode when branching, use non-interworking mov (to PC) instructions, which achieve the same thing.

The ADRL pseudo instruction is not an architectural construct, but a convenience macro that was supported by the ARM proprietary assembler and adopted by binutils GAS as well, but only when assembling in 32-bit ARM mode. Therefore, it can only be used in assembler code that is known to assemble in ARM mode only, but as it turns out, the Clang assembler does not implement ADRL at all, and so it is better to get rid of it entirely. So replace the ADRL instruction with a ADR instruction that refers to a nearer symbol, and apply the delta explicitly using an additional instruction.

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.

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.

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.

This patch adds support for EIP197 instances that include the output classifier (OCE) option, as used by one of our biggest customers. The OCE normally requires initialization and dedicated firmware, but for the simple operations supported by this driver, we just bypass it completely for now (using what is formally a debug feature).

At present, as HPRE/SEC/ZIP modules' parameter 'pf_q_num' is 1, kernel CRYPTO test will fail on the algorithms from the modules, since 'QP' hardware resources are not enough for CRYPTO TFM.

On systems with coherence issues, packet processed could succeed while it should have failed, e.g. because of an authentication fail. This is because the driver would read stale status information that had all error bits initialised to zero = no error. Since this is potential a security risk, we want to prevent it from being a possibility at all. So initialize all error bits to error state, so that reading stale status information will always result in errors.
