Also it forces CRYPTO_GHASH to be builtin even CRYPTO_DEV_VMX_ENCRYPT was configured as module. Update powerpc defconfigs and description in MAINTAINERS. Signed-off-by: Petr Vorel --- new in v2 This might be a bit aggressive, but IMHO CRYPTO_DEV_VMX only complicated things for nothing. But if you do *not* agree with removing it, I just add select to drivers/crypto/vmx/Kconfig (which forces dependencies to be always modules.) If it's ok for you to remove, please also check whether the description is ok. get_maintainer.pl script has size limitation: $ ./scripts/get_maintainer.pl drivers/crypto/vmx/Kconfig ... linux-crypto@vger.kernel.org (open list:IBM Power VMX Cryptographic Acceleration Instru...) maybe the name should be shorter.
