Subject: [PATCH] mm/page_alloc: Print node fallback order
References: git fixes (mm/pgalloc)
Patch-mainline: v5.16-rc1
Git-commit: 6cf253925df72e522c06dac09ede7e81a6e38121
Print information message about the allocation fallback order
for each NUMA node during boot.
No functional changes here. This makes it easier to illustrate
the problem in the node fallback list generation, which the
next patch fixes.
