Changes for v3.12 merge window

Changes for v3.12 merge window

[Bjorn Helgaas]

Here are the contents of my "next" branch, planned for release in v3.12.
Let me know if I'm missing something important.

In addition to what's already in "next", I hope to merge these for v3.12:

  - A fix for the pcie_cap_has_lnkctl()/pcie_get_minimum_link() problem
    reported by Yuval Mintz
  - The PCIe capability cleanups I posted today
  - Neil Horman's _OSC fix, which I think may fix a pciehp regression

I don't think the following will make it in this cycle:

  - Yijing Wang's Device Serial Number stuff.  I'm not happy with the
    VPD serial number support yet, and the whole series is a bit large
    for this late in the cycle.
  - Zhenzhong Duan's MSI/MSI-X rework.  Still waiting on some changelog
    updates.
