David updated the keys-asym-keyctl branch, and this patch set won't build 
any more.

The params member names have changed (now in_len and out_len).

The encrypt function for the key can now be called with 
params.key->type->asym_eds_op(). This also allows you to factor out the 
duplication in asym_key_encrypt, asym_key_decrypt, and asym_key_sign. See 
keyctl_pkey_e_d_s() in keyctl_pkey.c

key->type->asym_verify_signature() is available as well.
