Yes, I do prefer the syntax Luiz is proposing.
But I think it would be better if it made hugepages= and hugepagesz=
obsolete, so we can emit a printk if people use those, telling them
to migrate because the old options are going away.
Something like
hugepages_node=1:4:1G
and
hugepages_node=:16:1G
?
