Subject: [PATCH v2 0/7] SR-IOV fixes and cleanup

This is basically a revision of Alex's recent series:
http://lkml.kernel.org/r/20151027204607.14626.59671.stgit@localhost.localdomain

I squashed some fixes into the original patch, dropped two, and split
the rest up a little differently:

  iov: Update virtfn_max_buses to validate offset and stride
    Folded into the patch it fixed

  iov: Reset resources to 0 if totalVFs increases after enabling ARI
    Dropped on the theory that the resource allocation code
    should already handle this case

  iov: Fix sriov_enable exception handling path
    Split into a couple patches to make it easier to review

  iov: Variable and loop cleanup for sriov_disable and sriov_enable
    Dropped for readability

  iov: Update sriov_enable to correctly handle offset and stride
    Split into the piece that removes code made redundant by "PCI: Set
    SR-IOV NumVFs to zero after enumeration" and the piece that fixes
    the bug (using offset/stride before setting numVFs)

This is all on my pci/virtualization branch, and I'm still hoping to
merge this for v4.4.

Alexander Duyck (7):
      PCI: Set SR-IOV NumVFs to zero after enumeration
      PCI: Remove redundant validation of SR-IOV offset/stride registers
      PCI: Remove VFs in reverse order if virtfn_add() fails
      PCI: Reorder pcibios_sriov_disable()
      PCI: Wait 1 second between disabling VFs and clearing NumVFs
      PCI: Fix sriov_enable() error path for pcibios_enable_sriov() failures
      PCI: Set NumVFs before computing how many buses VFs require
