Jia-Ju Bai	7403bd14d7	PCI: hv: Replace GFP_ATOMIC with GFP_KERNEL in new_pcichild_device() ... new_pcichild_device() is not called in atomic context. The call chain ending up at new_pcichild_device() is: [1] new_pcichild_device() <- pci_devices_present_work() pci_devices_present_work() is only set in INIT_WORK(). Despite never getting called from atomic context, new_pcichild_device() calls kzalloc with GFP_ATOMIC, which waits busily for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL to avoid busy waiting.

Shawn Lin	6e0832fa43	PCI: Collect all native drivers under drivers/pci/controller/ ... 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.
