I am agree about massive amount of changes, though I thought Anatoly sort of volunteering for it :)
About benefit - it would save us spilling/restoring one register for each rte_malloc() call.
Probably not that important, as  rte_malloc() usually is used from data-path, but still. 
Plus it doesn't look good to have a function with parameter  that would never be used.
