[PATCH v4 0/2] Reset PCIe devices to address DMA problem on kdump with iommu

These patches reset PCIe devices at boot time to address DMA problem on kdump with iommu. When "reset_devices" is specified, a hot reset is triggered on each PCIe root port and downstream port to reset its downstream endpoint. Background: A kdump problem about DMA has been discussed for a long
