Subject: [GIT PULL] PCI fixes for v3.17

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
