GCM is y but AEAD is only m, yet GCM selects AEAD. Perhaps a kbuild
bug?

Thanks Herbert, currently we use make randconfig to generate this kconfig file, is it possible this is still a valid settings?

Sorry I didn't mean kbuild as in your build system, but kbuild as in
the kernel kbuild subsystem.
AFAICS, the Kconfig rules should forbid the situation in your
config file where GCM=y but AEAD=m because GCM selects AEAD. So
the fact that it happened either means that there is something
that I am missing or that the kbuild subsystem is buggy.
Cheers,
