The patch titled
Subject: i40e: use numa_mem_id() to better support memoryless node
has been removed from the -mm tree. Its filename was
i40e-use-numa_mem_id-to-better-support-memoryless-node.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Jiang Liu <jiang.liu@xxxxxxxxxxxxxxx>
Subject: i40e: use numa_mem_id() to better support memoryless node
i40e_clean_rx_irq() tries to reuse memory pages allocated from the nearest
node. To better support memoryless node, use numa_mem_id() instead of
numa_node_id() to get the nearest node with memory.
This change should only affect performance.
