I do actually try to read the explanations..

However, I also do build testing, which seems to have been missing. Notably:

> Ho-Ren (Jack) Chuang (1):
>      memory tier: consolidate the initialization of memory tiers

causes

  WARNING: modpost: vmlinux: section mismatch in reference:
hmat_set_default_dram_perf+0xc (section: .text) -> default_dram_nodes
(section: .init.data)
  WARNING: modpost: vmlinux: section mismatch in reference:
hmat_set_default_dram_perf+0x6c (section: .text) -> default_dram_nodes
(section: .init.data)

and sure enough, default_dram_nodes() is an init section, and is
accessed from hmat_set_default_dram_perf().

I think the fix is to just mark hmat_set_default_dram_perf() as an
init function too. Testing that now.
