Is "Power10+" a specific architecture or does that mean "Power10 or later"?

Please follow the newer wording conventions for the menu item and
help text, more like:

config CRYPTO_AES_GCM_PPC_P10
        tristate "AEAD cipher: AES in GCM mode (Power10)"

        help
          AEAD cipher: AES cipher algorithms (FIPS-197) with
	   GCM (Galois/Counter Mode) authenticated encryption mode (NIST SP800-38D=
)

          Architecture: powerpc64 using:
          - little-endian
          - Power10 features=20

          [some description here]

Also, all the other powerpc cra_driver_names follow=20
	alg-arch
not
	arch-alg

so=20
	.base.cra_driver_name	=3D "p10_aes_gcm",
might be better as
	.base.cra_driver_name	=3D "aes-gcm-p10",

Patch 4 seems to have code for lots of other modes like CBC and XTS.
Does the perl script strip out all of that?
