Disabling it on m68k could be a first step (any WiFi drivers supported
on m68k yet?).
Making it tristate is non-trivial, as there are some interdependencies:
security/keys/Makefile:compat-obj-$(CONFIG_KEY_DH_OPERATIONS) += compat_dh.o
security/keys/Makefile:obj-$(CONFIG_KEY_DH_OPERATIONS) += dh.o
security/keys/internal.h:#ifdef CONFIG_KEY_DH_OPERATIONS
security/keys/keyctl.c:
(IS_ENABLED(CONFIG_KEY_DH_OPERATIONS) ? KEYCTL_CAPS0_DIFFIE_HELLMAN
: 0) |
