2018-06-28	PCI: vmd: White list for fast interrupt handlers	Keith Busch	1	-1/+12
	Devices with slow interrupt handlers are significantly harming performance when their interrupt vector is shared with a fast device. Create a class code white list for devices with known fast interrupt handlers and let all other devices share a single vector so that they don't interfere with performance. At the moment, only the NVM Express class code is on the list, but more may be added if VMD users desire to use other low-latency devices in these domains.

2018-06-08	PCI: Collect all native drivers under drivers/pci/controller/	Shawn Lin	1	-0/+870
	Native PCI drivers for root complex devices were originally all in drivers/pci/host/. Some of these devices can also be operated in endpoint mode. Drivers for endpoint mode didn't seem to fit in the "host" directory, so we put both the root complex and endpoint drivers in per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc. These per-device directories contain trivial Kconfig and Makefiles and clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and collect all the device-specific drivers there. No functional change intended.
