Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull crypto library updates from Eric Biggers:

 - Migrate the x86 and riscv optimized implementations of various AES
   modes (ECB, CBC, CBC-CTS, CTR, XCTR, XTS) into lib/crypto/.

   This makes the library APIs be properly accelerated on these
   architectures, while still accelerating crypto_skcipher as well.

   It removes a lot of redundant glue code, since the crypto API
   boilerplate no longer needs to be duplicated for these architectures.

   It also fixes the longstanding issue where optimizations for these
   AES modes were disabled by default on these architectures.

 - Optimize AES-XTS on SPARC64 using the SPARC crypto opcodes

 - Move the SipHash code into lib/crypto/

 - Update the ChaCha and Poly1305 functions to take size_t lengths,
   resolving issues where lengths over INT_MAX were mishandled

 - Make frame pointer unwinding work properly in some of the x86
   assembly functions, by following the standard %rbp convention

 - Add helper functions for zeroizing structs

 - Make a few documentation improvements
