This still doesn't suffice:

ERROR: "get_matching_microcode" [arch/x86/kernel/microcode.ko] undefined!
ERROR: "microcode_sanity_check" [arch/x86/kernel/microcode.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
make: *** Waiting for unfinished jobs....

.config attached.

And by quickly grepping through it, none of the new options are there:

obj-$(CONFIG_MICROCODE_EARLY)		+= microcode_core_early.o
obj-$(CONFIG_MICROCODE_INTEL_EARLY)	+= microcode_intel_early.o
obj-$(CONFIG_MICROCODE_INTEL_LIB)	+= microcode_intel_lib.o
microcode-y				:= microcode_core.o

which most probably causes the build error. AFAICT, you need to pull up
the arch/x86/Kconfig changes from 11/11 too.

HTH.
