From 325ef1857fff8b2049322921e19421b6c5ad74e5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 12 Apr 2018 09:33:30 +0200 Subject: PCI: remove PCI_DMA_BUS_IS_PHYS This was used by the ide, scsi and networking code in the past to determine if they should bounce payloads. Now that the dma mapping always have to support dma to all physical memory (thanks to swiotlb for non-iommu systems) there is no need to this crude hack any more.
