Subject: [PATCH 00/15] Finish disentangling ChaCha, Poly1305, and BLAKE2s from CRYPTO

This series removes the unnecessary dependency of the ChaCha, Poly1305,
and BLAKE2s library functions on the generic crypto infrastructure, i.e.
CONFIG_CRYPTO.  To do this, it moves arch/*/crypto/Kconfig from a
submenu of crypto/Kconfig to a submenu of arch/*/Kconfig, then re-adds
the CRYPTO dependency to the symbols that actually need it.

Patches 14-15 then simplify the ChaCha and Poly1305 symbols by removing
the unneeded "internal" symbols.

Note that Curve25519 is still entangled.  Later patches will fix that.

Eric Biggers (15):
  crypto: arm - remove CRYPTO dependency of library functions
  crypto: arm64 - drop redundant dependencies on ARM64
  crypto: arm64 - remove CRYPTO dependency of library functions
  crypto: loongarch - source arch/loongarch/crypto/Kconfig without
    CRYPTO
  crypto: mips - remove CRYPTO dependency of library functions
  crypto: powerpc - drop redundant dependencies on PPC
  crypto: powerpc - remove CRYPTO dependency of library functions
  crypto: riscv - remove CRYPTO dependency of library functions
  crypto: s390 - drop redundant dependencies on S390
  crypto: s390 - remove CRYPTO dependency of library functions
  crypto: sparc - source arch/sparc/crypto/Kconfig without CRYPTO
  crypto: x86 - drop redundant dependencies on X86
  crypto: x86 - remove CRYPTO dependency of library functions
  crypto: lib/chacha - remove INTERNAL symbol and selection of CRYPTO
  crypto: lib/poly1305 - remove INTERNAL symbol and selection of CRYPTO
