Subject: [PATCH 1/6] crypto: curve25519 - Remove kpp support
Currently, Curve25519 has both a library API and a crypto_kpp API.
However, the crypto_kpp API to Curve25519 has no users outside
crypto/testmgr.c. I.e., no non-test code ever passes "curve25519" to
crypto_alloc_kpp(). And the crypto/testmgr.c test coverage for
Curve25519 isn't particularly useful either, since it just runs the same
list of test vectors that curve25519-selftest uses.
Therefore, all the crypto_kpp support for Curve25519 is unnecessary.
Remove it. We'll instead focus on the Curve25519 library API, which is
the API that is actually being used. Curve25519 remains fully supported
for in-kernel users via the library API (crypto/curve25519.h).
