As Yang pointed out, why not just use CONFIG_NUMA?  I suspect the
added value of CONIFIG_TIRED_MEMORY.

I decided to use TIERED_MEMORY to bring more clarity. It should be same
now that we have moved CONFIG_MIGRATION dependencies to runtime. IMHO
having CONFIG_TIERED_MEMORY is better than using CONFIG_NUMA.

I don't think CONFIG_TIERED_MEMORY bring no much value.  It's better
to use CONFIG_NUMA directly.  But this is just my opinion.

I agree. As long as it's always built with CONFIG_NUMA, it's simply
NUMA code. Easy enough to modularize it later if somebody really wants
this to be configurable separately.

I was comparing,

#ifdef CONFIG_TIERED_MEMORY
struct memory_tier {

vs

#ifdef CONFIG_NUMA
struct memory_tier {

I will switch to CONFIG_NUMA in the next update since you are not finding it beneficial.
