Get rid of pointless indirect calls where the target of the call is decided
at boot and never changes. Also, make the size of the key struct variable,
and only carry the extra keys needed for aggregation when using a version
of the algorithm that makes use of them.

Ard Biesheuvel (5):
  crypto: arm64/ghash - drop PMULL based shash
  crypto: arm64/gcm - disentangle ghash and gcm setkey() routines
  crypto: arm64/gcm - use variably sized key struct
  crypto: arm64/gcm - use inline helper to suppress indirect calls
  crypto: arm/ghash - use variably sized key struct

All applied.  Thanks.
