The recently added NUMA changes (merged for v5.5) to page_pool, it both contains a bug in handling NUMA_NO_NODE condition, and added code to the fast-path.
This patchset fixes the bug and moves code out of fast-path. The first patch contains a fix that should be considered for 5.5. The second patch reduce code size and overhead in case CONFIG_NUMA is disabled.
Currently the NUMA_NO_NODE setting bug only affects driver 'ti_cpsw' (drivers/net/ethernet/ti/), but after this patchset, we plan to move other drivers (netsec and mvneta) to use NUMA_NO_NODE setting.
