This change log needs to stand on its own. ie. it needs to explain what the problem is and why the feature is being disabled, without reference to subsequent patches (which will probably be merged separately). It should also have a Fixes/stable tag. And as Christophe said, just adding a dependency on BROKEN is sufficient. cheers > diff --git a/arch/powerpc/crypto/Kconfig b/arch/powerpc/crypto/Kconfig > index 09ebcbdfb34f..96ca2c4c8827 100644 > --- a/arch/powerpc/crypto/Kconfig > +++ b/arch/powerpc/crypto/Kconfig > @@ -105,22 +105,22 @@ config CRYPTO_AES_PPC_SPE > architecture specific assembler implementations that work on 1KB > tables or 256 bytes S-boxes. > > -config CRYPTO_AES_GCM_P10 > - tristate "Stitched AES/GCM acceleration support on P10 or later CPU (PPC)" > - depends on PPC64 && CPU_LITTLE_ENDIAN && VSX > - select CRYPTO_LIB_AES > - select CRYPTO_ALGAPI > - select CRYPTO_AEAD > - select CRYPTO_SKCIPHER > - help > - AEAD cipher: AES cipher algorithms (FIPS-197) > - GCM (Galois/Counter Mode) authenticated encryption mode (NIST SP800-38D) > - Architecture: powerpc64 using: > - - little-endian > - - Power10 or later features > - > - Support for cryptographic acceleration instructions on Power10 or > - later CPU.
