Merge tag 'pci-v4.7-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI fix from Bjorn Helgaas:
 "Here's a small fix for v4.7.  This problem was actually introduced in
  v4.6 when we unified Kconfig, making PCIe support available everywhere
  including sparc, where config reads into unaligned buffers cause
  warnings.  This fix is from Dave Miller.

  As a reminder, any future PCI fixes for v4.7 will probably come from
  Alex Williamson, since I'll be on vacation for most of the rest of
  this cycle.  I should be back about the time the merge window opens"
