One more thing:

This screams for adding a directory called "microcode" in the kernel
sources and moving all the microcode-related files there. IOW:

arch/x86/kernel/cpu/microcode/core.c
arch/x86/kernel/cpu/microcode/core_early.c
arch/x86/kernel/cpu/microcode/intel.c
arch/x86/kernel/cpu/microcode/amd.c
...

And yes, they should be under "cpu" too.
