<title>lib/crc: make arch-optimized code use subsys_initcall</title>

<content type='text'>
Make the architecture-optimized CRC code do its CPU feature checks in
subsys_initcalls instead of arch_initcalls.  This makes it consistent
with arch/*/lib/crypto/ and ensures that it runs after initcalls that
possibly could be a prerequisite for kernel-mode FPU, such as x86's
xfd_update_static_branch() and loongarch's init_euen_mask().

Note: as far as I can tell, x86's xfd_update_static_branch() isn't
*actually* needed for kernel-mode FPU.  loongarch's init_euen_mask() is
needed to enable save/restore of the vector registers, but loongarch
doesn't yet have any CRC or crypto code that uses vector registers
anyway.  Regardless, let's be consistent with arch/*/lib/crypto/ and
robust against any potential future dependency on an arch_initcall.

This reverts commit c4741b23059794bd99beef0f700103b0d983b3fd.

Crypto API self-tests no longer run at registration time and now
occur either at late_initcall or upon the first use.

Therefore the premise of the above commit no longer exists.  Revert
it and subsequent additions of subsys_initcall and arch_initcall.

Note that lib/crypto calls will stay at subsys_initcall (or rather
downgraded from arch_initcall) because they may need to occur
before Crypto API registration.

Instead of providing crypto_shash algorithms for the arch-optimized
SHA-256 code, instead implement the SHA-256 library.  This is much
simpler, it makes the SHA-256 library functions be arch-optimized, and
it fixes the longstanding issue where the arch-optimized SHA-256 was
disabled by default.  SHA-256 still remains available through
crypto_shash, but individual architectures no longer need to handle it.

<title>sparc/crc: drop "glue" from filenames</title>

<id>ee858d83c59d95e08551a9dc270bedca4b72137d</id>
<content type='text'>
The use of the term "glue" in filenames is a Crypto API-ism that rarely
shows up elsewhere in lib/ or arch/*/lib/.  I think adopting it there
was a mistake.  The library just uses standard functions, so the amount
of code that could be considered "glue" is quite small.  And while often
the C functions just wrap the assembly functions, there are also cases
like crc32c_arch() in arch/x86/lib/crc32-glue.c that blur the line by
in-lining the actual implementation into the C function.  That's not
"glue code", but rather the actual code.

Therefore, let's drop "glue" from the filenames and instead use e.g.
crc32.c instead of crc32-glue.c.

All of the CRC library's CPU feature static_keys are initialized by
initcalls and never change afterwards, so there's no need for them to be
in the regular .data section.  Put them in .data..ro_after_init instead.

Castagnoli CRC32 instead of the previous mix of crc32c(), crc32c_le(),
and __crc32c_le(), make the same change to the underlying base and arch

<content type='text'>
Move the sparc CRC32C assembly code into the lib directory and wire it
up to the library interface.  This allows it to be used without going
through the crypto API.  It remains usable via the crypto API too via
the shash algorithms that use the library interface.  Thus all the
arch-specific "shash" code becomes unnecessary and is removed.

Move the sparc CRC32C assembly code into the lib directory and wire it
up to the library interface.  This allows it to be used without going
through the crypto API.  It remains usable via the crypto API too via
the shash algorithms that use the library interface.  Thus all the
arch-specific "shash" code becomes unnecessary and is removed.
