Re: [PATCH v7 05/15] swiotlb: Add a new get_io_tlb_mem getter
From: Claire Chang <hidden>

Also in:
dri-devel, intel-gfx, linux-devicetree, linux-iommu, linux-pci, lkml, xen-devel
Still keep this function because directly using dev->dma_io_tlb_mem will cause issues for memory allocation for existing devices. The pool can't support atomic coherent allocation so we need to distinguish the per device pool and the default pool in swiotlb_alloc.
