everything was taken from nvgpu. Main reason for adding is to improve stability of the PCIe link changing code as we might want to depend on it for a workaround fixing our infamous runpm issues on recent laptops Karol Herbst (3): pci: force disable ASPM before changing the link speed pci/gk104: enable dl_mgr safe mode pci/gk104: wait for ltssm idle before changing the link

not much changed since the last time I sent those patches out, but there are a couple of annoying bug fixes, which users would probably never hit unless they do rmmod/modprobe nouveau cycles. Biggest change is that I force the link to a 8.0 speed rather than the speed the GPU came up with. Also this series depends on the PCIe improvement patches I sent out recently. Karol Herbst (4): pci:
