Heh, I just merged your series into mine for orphans (just sent it too)
and ironically, I did this too (rebase to rc7) but for ARM fixes on
Clang vs binutils AS.
Ganapatrao Kulkarni has put some effort on making arm-smmu-v3 use local
memory to save command queues[1]. I also did similar job in patch
"iommu/arm-smmu-v3: allocate the memory of queues in local numa node"
[2] while not realizing Ganapatrao has done that before.
But it seems it is much better
Right now, drivers like ARM SMMU are using dma_alloc_coherent() to get
coherent DMA buffers to save their command queues and page tables. As
there is only one default CMA in the whole system, SMMUs on nodes other
than node0 will get remote memory. This leads to significant latency.

Right now, smmu is using dma_alloc_coherent() to get memory to save queues

node0, which could be far away from node2, node3 etc.
