Merge tag 'scoped-ksimd-for-arm-arm64' into libcrypto-fpsimd-on-stack
Pull scoped ksimd API for ARM and arm64 from Ard Biesheuvel:
"Introduce a more strict replacement API for
kernel_neon_begin()/kernel_neon_end() on both ARM and arm64, and
replace occurrences of the latter pair appearing in lib/crypto"
