Merge tag 'libcrypto-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux
Pull crypto library fixes from Eric Biggers:
- Fix a performance issue with the scoped_ksimd() macro (new in 6.19)
where it unnecessarily initialized the entire fpsimd state.
- Add a missing gitignore entry for a generated file added in 6.18.
