The other two are attached. I suppose the ordering doesn't matter.

Ok, the eth link cable hotplugging issue seems fixed, plugging and
unplugging the cable works as expected.

Q: what happened to those, are they going upstream for 3.9 or are you
sending them now for 3.8?

They fix at least the cable hotplugging issue so at least one thing is

I haven't done anything with the e1000e patches; I assume the e1000e
maintainers will take care of those.

I merged the following patches for v3.9:

* pci/konstantin-runtime-pm:
PCI/PM: Clear state_saved during suspend
PCI: Use atomic_inc_return() rather than atomic_add_return()
PCI: Catch attempts to disable already-disabled devices
PCI: Disable Bus Master unconditionally in pci_device_shutdown()

You can see the actual patches I merged at:;a=shortlog;h=refs/heads/next

It's pretty late for v3.8, but let me know if you think they're critical.

Ok, I meant those:

They fix the link detection issue on my x230. So let's see. The first one is:

* (e1000e: fix pci device enable
counter balance)

please use this instead:

[PATCH v2 1/7] e1000e: fix pci-device enable-counter balance

from v2 patchset:

Rafael said this one is a real bugfix. Looks like e1000e maintainers are
picking that one?

* pci-pm-fix-e1000e-runtime-suspend.patch

I don't see that one in your tree.

* pci-pm-clear-state_saved-during-suspend.patch

I can see this one in your tree:;a=commitdiff;h=82fee4d67ab86d6fe5eb0f9a9e988ca9d654d765

With the imminence of the 3.8 release, we probably want to wait for
after the merge window and retest again, then apply and packport stuff,
if needed.

And the NMI issue is still unfixed so this needs more work, AFAICT. Oh
well, after the merge window.
