Merge branch 'rfs-use-high-order-allocations-for-hash-tables'

Eric Dumazet says:

====================
rfs: use high-order allocations for hash tables

This series adds rps_tag_ptr which encodes both a pointer
and a size of a power-of-two hash table in a single long word.

RFS hash tables (global and per rx-queue) are converted to rps_tag_ptr.

This removes a cache line miss, and allows high-order allocations.

The global hash table can benefit from huge pages.
