Modernize vga_switcheroo by using a "device link" to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into. Remove thereby obsoleted code and fix a bunch of bugs. Device links were introduced in v4.10. Users might see a small power saving if the discrete GPU is in use and its HDA controller is not, because the HDA controller is now allowed to runtime

Modernize vga_switcheroo by using a device link to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into, v2. Changes since v1: - Replace patch [1/7] to use pci_save_state() / pci_restore_state() for consistency between runtime PM code path of bound and unbound devices. (Rafael, Bjorn) - Patch [5/7]: Drop an unnecessary initialization. (Bjorn) Rephrase

Hi Jan, Attached patch dumps io page fault flags. The flags show the reason of the fault and tell us if this is an unmapped interrupt fault or a DMA fault.
