2018-05-07PCI: remove PCI_DMA_BUS_IS_PHYSChristoph Hellwig
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.

2017-09-26RISC-V: Device, timer, IRQs, and the SBIPalmer Dabbelt
This patch contains code that interfaces with devices that are mandated by the RISC-V supervisor specification and that don't have explicit drivers anywhere else in the tree. This includes the staticly defined interrupts, the CSR-mapped timer, and virtualized SBI devices. Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>
