2025-04-28crypto: powerpc - move library functions to arch/powerpc/lib/crypto/Eric Biggers
Continue disentangling the crypto library functions from the generic crypto infrastructure by moving the powerpc ChaCha and Poly1305 library functions into a new directory arch/powerpc/lib/crypto/ that does not depend on CRYPTO. This mirrors the distinction between crypto/ and lib/crypto/. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-04-19crypto: lib/poly1305 - restore ability to remove modulesEric Biggers
Though the module_exit functions are now no-ops, they should still be defined, since otherwise the modules become unremovable.

2025-04-16crypto: poly1305 - centralize the shash wrappers for arch codeEric Biggers
Following the example of the crc32, crc32c, and chacha code, make the crypto subsystem register both generic and architecture-optimized poly1305 shash algorithms, both implemented on top of the appropriate library functions. This eliminates the need for every architecture to implement the same shash glue code. Note that the poly1305 shash requires that the key be prepended to the data, which differs from the library functions where the key is simply a parameter to poly1305_init(). Previously this was handled at a fairly low level, polluting the library code with shash-specific code. Reorganize things so that the shash code handles this quirk itself. Also, to register the architecture-optimized shashes only when architecture-optimized code is actually being used, add a function poly1305_is_arch_optimized() and make each arch implement it. Change each architecture's Poly1305 module_init function to arch_initcall so that the CPU feature detection is guaranteed to run before poly1305_is_arch_optimized() gets called by crypto/poly1305.c. (In cases where poly1305_is_arch_optimized() just returns true unconditionally, using arch_initcall is not strictly needed, but it's still good to be consistent across architectures.)

2025-04-16crypto: powerpc/poly1305 - implement library instead of shashEric Biggers
Currently the Power10 optimized Poly1305 is only wired up to the crypto_shash API, which makes it unavailable to users of the library API. The crypto_shash API for Poly1305 is going to change to be implemented on top of the library API, so the library API needs to be supported. And of course it's needed anyway to serve the library users. Therefore, change the Power10 optimized Poly1305 code to implement the library API instead of the crypto_shash API.

2024-10-02move asm/unaligned.h to linux/unaligned.hAl Viro
asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h
