A lot of SCSI drivers still use the legacy PCI DMA API. While a few of
them have various oddities that should be deal with separately, most of
them can be very trivially converted over.
Two interesting things to look out for:
- pci_(z)alloc_consistent forced GFP_ATOMIC allocations, which is a bad
idea almost all the time. All these patches switch over to GFP_KERNEL.
The few drivers were we can't do this will be deal with separately.
- a lot of odd things were going on when setting the dma mask. This
series switches to use dma_set_mask_and_coherent where possible.
Change since v1:
- minor indentation and comment fixups
- collected various reviewed-by/acked-by/tested-by tags
