[RESEND PATCH v2 3/6] PCI: Set PCI_BUS_FLAGS_MSI_REMAP if IOMMU have capability of IRQ remapping

2016-06-01 Thread Yongji Xie
The capability of IRQ remapping is abstracted on IOMMU side on some archs. There is a existing flag IOMMU_CAP_INTR_REMAP for this. To have a universal flag to test this capability for different archs on PCI side, we set PCI_BUS_FLAGS_MSI_REMAP for PCI buses when IOMMU_CAP_INTR_REMAP is set. Signe
