Subject: [PATCH 0/9] lib/crypto: move arch/$(ARCH)/lib/crypto/ to lib/crypto/$(ARCH)/
This series applies on top of
https://lore.kernel.org/r/20250616014019.415791-1-ebiggers@kernel.org/
and is also available in git at:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git arch-to-lib-crypto-v1
This series moves the contents of arch/$(ARCH)/lib/crypto/ into
lib/crypto/$(ARCH)/.
The new code organization makes a lot more sense for how this code
actually works and is developed. In particular, it makes it possible to
build each algorithm as a single module, with better inlining and dead
code elimination. For a more detailed explanation, see the patchset
which did this for the CRC library code:
https://lore.kernel.org/r/20250607200454.73587-1-ebiggers@kernel.org/.
Also see the patchset which did this for SHA-512:
https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/
This is just a preparatory series, which does the move to get the files
into their new location but keeps them building the same way as before.
Later patch series will make the actual improvements to the way the
arch-optimized code is integrated for each algorithm.
Note that .gitignore files are being intentionally kept for now. See
https://lore.kernel.org/r/CAHk-=whu2fb22rEy6+oKx1-+NCHuWucZepvD0H2MD38DrJVKtg@mail.gmail.com/
I'll remove it later after some time has passed.
