[PATCH 0/3] PCIe link change improvements
...g 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

[PATCH 0/6] Add workaround for fixing runpm
...since last sent:
* reworked the ASPM patch
* removed "pci: add nvkm_pcie_get_speed" patch
Please test this on Laptops and report back if it either breaks something
or doesn't fix runpm.
Thanks

[PATCH 0/8] Add workaround for fixing runpm
...it, came up with a
different approach and forgot to delete it, doesn't hurt though)
* expose information about runtime suspending to nvkm so that we can run
the pcie workaround only on runtime suspend
