Factor out the blacklist hash creation with the get_raw_hash() helper.
This also centralize the "tbs" and "bin" prefixes and make them private,
which help to manage them consistently.

<title>crypto: cryptd - Protect per-CPU resource by disabling BH.</title>

<id>91e8bcd7b4da182e09ea19a2c73167345fe14c98</id>
<content type='text'>
The access to cryptd_queue::cpu_queue is synchronized by disabling
preemption in cryptd_enqueue_request() and disabling BH in
cryptd_queue_worker(). This implies that access is allowed from BH.

If cryptd_enqueue_request() is invoked from preemptible context _and_
soft interrupt then this can lead to list corruption since
cryptd_enqueue_request() is not protected against access from
soft interrupt.

Replace get_cpu() in cryptd_enqueue_request() with local_bh_disable()
to ensure BH is always disabled.
Remove preempt_disable() from cryptd_queue_worker() since it is not
needed because local_bh_disable() ensures synchronisation.

As was established in the thread
https://lore.kernel.org/linux-crypto/20220223080400.139367-1-gilad@benyossef.com/T/#u,
many crypto API users doing in-place en/decryption don't use the same
scatterlist pointers for the source and destination, but rather use
separate scatterlists that point to the same memory.  This case isn't
tested by the self-tests, resulting in bugs.

This is the natural usage of the crypto API in some cases, so requiring
API users to avoid this usage is not reasonable.

Therefore, update the self-tests to start testing this case.

The lib/crypto libraries live in lib because they are used by various
drivers of the kernel. In contrast, the various helper functions in
crypto are there because they're used exclusively by the crypto API. The
SM3 and SM4 helper functions were erroniously moved into lib/crypto/
instead of crypto/, even though there are no in-kernel users outside of
the crypto API of those functions. This commit moves them into crypto/.
