-Subject: [PATCH 072/203] PCI: Introduce new MSI chip infrastructure
-
-The new struct msi_chip is used to associated an MSI controller with a
-PCI bus. It is automatically handed down from the root to its children
-during bus enumeration.
-
-This patch provides default (weak) implementations for the architecture-
-specific MSI functions (arch_setup_msi_irq(), arch_teardown_msi_irq()
-and arch_msi_check_device()) which check if a PCI device's bus has an
-attached MSI chip and forward the call appropriately.
