Subject[PATCH 0/4] dma-pool: Fix atomic pool selection
Date
This is my attempt at fixing one of the regressions we've seen[1] after
the introduction of per-zone atomic pools.

This combined with "dma-pool: Do not allocate pool memory from CMA"[2]
should fix the boot issues on Jeremy's RPi4 setup.

Nicolas Saenz Julienne (4):
dma-direct: Provide function to check physical memory area validity
dma-pool: Get rid of dma_in_atomic_pool()
dma-pool: Introduce dma_guess_pool()
dma-pool: Make sure atomic pool suits device
