* crypto: arm64/nhpoly1305 - eliminate unnecessary CFI wrapperEric Biggers2022-11-251-2/+3
| | | | | | | | | | Since the CFI implementation now supports indirect calls to assembly functions, take advantage of that rather than use a wrapper function.

* crypto: arm64 - Use modern annotations for assembly functionsMark Brown2019-12-201-2/+2
| | | | | | | | | | | | | | | | In an effort to clarify and simplify the annotation of assembly functions in the kernel new macros have been introduced. These replace ENTRY and ENDPROC and also add a new annotation for static functions which previously had no ENTRY equivalent. Update the annotations in the crypto code to the new macros. There are a small number of files imported from OpenSSL where the assembly is generated using perl programs, these are not currently annotated at all and have not been modified.

* crypto: arm64/nhpoly1305 - add NEON-accelerated NHPoly1305Eric Biggers2018-12-131-0/+103
Add an ARM64 NEON implementation of NHPoly1305, an ε-almost-∆-universal hash function used in the Adiantum encryption mode. For now, only the NH portion is actually NEON-accelerated; the Poly1305 part is less performance-critical so is just implemented in C.
