Yeah, it isn't difficult at all.  After the series, emulation code is
isolated into <400 lines of code and the states it modifies is
immediately apparent.  We can just move all the functions inside
CONFIG_NUMA_EMU and let initmem_init() pass all the states which are
necessary for emulation to numa_emulation().  If that's desirable,
I'll send a patch to do that on top once the whole thing settles a
bit.

Thanks.
