rte_cldemote is similar to a prefetch hint - in reverse. cldemote(addr)
enables software to hint to hardware that line is likely to be shared.
Useful in core-to-core communications where cache-line is likely to be
shared. ARM and PPC implementation is provided with NOP and can be added
if any equiv
We are including this in rte_prefetch.h since it is the most closely
related code location.rte_cldemte is similar to a prefetch hint -in reverse
