[PATCH 3/5] PCI: Set PCI_BUS_FLAGS_MSI_REMAP if MSI controller supports IRQ remapping

2016-04-27 Thread Yongji Xie
On ARM HW the capability of IRQ remapping is abstracted on MSI controller side. MSI_FLAG_IRQ_REMAPPING is used to advertise this [1]. 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 MSI_FLAG_IRQ_REMAPPING is set.
