This is some rework of David's series to preserve ASPM L1 substate
configuration across suspend/resume.

David E. Box (5):
PCI/ASPM: Move pci_configure_ltr() to aspm.c
PCI/ASPM: Always build aspm.c
PCI/ASPM: Move pci_save_ltr_state() to aspm.c
PCI/ASPM: Save L1 PM Substates Capability for suspend/resume
PCI/ASPM: Call pci_save_ltr_state() from pci_save_pcie_state()

I applied these as pci/aspm for v6.9, replacing the original unlabeled
v6 that has been in -next.
Would anybody be able to test this, particularly to make sure it works
for the bugs we're claiming to fix with this series?

This series is headed for v6.9, and I hope we can finally claim
victory over these issues.
This is in -next as of the Mar 7 tree. Or if you want just the ASPM
changes, based on v6.8-rc1, you can use the branch at

I just tested the patch v7 from Bjorn, it works on my Asus UX305FA.
Tested on kernel v6.8-rc1.
