So this is my report of the regression I'd found with Bjorn's original commit:

Subject: Commit 4257f7e0 ("PCI/ASPM: Save/restore L1SS Capability for suspend/resume") causing hibernate resume
    failures

I've been running Linus' master branch on my laptop (Dell XPS 13 2-in-1). With
this commit in place, after resuming from hibernate my machine is essentially
useless, with a torrent of disk I/O errors on my NVMe device (at least, and
possibly other devices affected) until a reboot.

I do use tlp to set the PCIe ASPM to "performance" on AC and "powersupersave"
on battery.

Let me know if you need more information.
----

I just reapplied it on top of Linus' master and not only did it go in cleanly(!),
NOW I'm not getting any issues after a suspend/resume. I've attached the output
of "lspci -vvvvnn" before a hibernation (but not the very *first* one; if you
need that output, let me know) and will submit the same post-hibernation (which
is the same as the pre-hibernation case) and the post-suspend case (which is
slightly different) in subsequent E-mails (due to attachment size).
