Applied to for-linus-4.6, thanks.

I rewrote some of the commit messages for clarity.  Please only put
relevant information in them and for regression fixes, make sure it's
clear what functionality regressed.

e.g. #1 now reads:

    Commit 408fb0e5aa7fda0059db282ff58c3b2a4278baa0 (xen/pciback: Don't
    allow MSI-X ops if PCI_COMMAND_MEMORY is not set) prevented enabling
    MSI-X on passed-through virtual functions, because it checked the VF
    for PCI_COMMAND_MEMORY but this is not a valid bit for VFs.

    Instead, check the physical function for PCI_COMMAND_MEMORY.
