Bailey Forrest d991666b7b gve: make IRQ handlers and page allocation NUMA aware ... All memory in GVE is currently allocated without regard for the NUMA node of the device. Because access to NUMA-local memory access is significantly cheaper than access to a remote node, this change attempts to ensure that page frags used in the RX path, including page pool frags, are allocated on the NUMA node local to the gVNIC device. Note that this attempt is best-effort. If necessary, the driver will still allocate non-local memory, as __GFP_THISNODE is not passed. Descriptor ring allocations are not updated, as dma_alloc_coherent handles that. This change also modifies the IRQ affinity setting to only select CPUs from the node local to the device, preserving the behavior that TX and RX queues of the same index share CPU affinity.
