[pull] [SRU][Zesty]PCI: Add pci_mmap_resource_range() and use it for ARM64

[Manoj Iyer]

Please review and consider this pull request for Zesty to address bug 
https://launchpad.net/bugs/1712580 where without this patch uio device 
binding inside VM would fail with errors. This patch was requested by 
Qualcomm for their QDF2400 system. The test kernel is available at
https://launchpad.net/~centriq-team/+archive/ubuntu/lp1712580/ and was 
tested by me on QDF2400 system. The patches touch PCI subsystem on all 
architecures and PCI drivers, I have regression tested it on AMD64 and 
PPC64EL systems and posted those results to the bug report.

  PCI: Add pci_mmap_resource_range() and use it for ARM64 (2017-08-24 
11:28:13 -0500)

----------------------------------------------------------------
David Woodhouse (4):
      PCI: Move multiple declarations of pci_mmap_page_range() to 
<linux/pci.h>
      PCI: Use BAR index in sysfs attr->private instead of resource 
pointer
      PCI: Add BAR index argument to pci_mmap_page_range()
      PCI: Add pci_mmap_resource_range() and use it for ARM64
