[GIT PULL] PCI fixes for v3.17
From: Bjorn Helgaas
Date: Wed Sep 24 2014 - 12:07:04 EST
Hi Linus,
Here are a few fixes that should be in v3.17.
- Reverting "Don't scan random busses" covers up a CardBus regression
having to do with allocating CardBus bus numbers.
- Reverting "Make sure bus numbers stay within parents bounds" covers up
an ACPI _CRS bug that makes us reconfigure a bridge, causing a broken
device behind it to stop responding.
- The pciehp timeout change fixes some code we added in v3.17. Without
the fix, we can send a new hotplug command too early, before the
timeout has expired.
I hope for better fixes for the reverts, but those will have to come after
v3.17.
Bjorn
