[PATCH 0/3] PCIe link change improvements
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

[PATCH v4 0/4] add PCIe workaround to fix runpm on laptops
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.
