Merge branch 'pci/resource-mmap' into next
* pci/resource-mmap:
ia64: Use generic pci_mmap_resource_range()
ia64: Remove redundant checks for WC in pci_mmap_page_range()
ia64: Remove redundant valid_mmap_phys_addr_range() from pci_mmap_page_range()
PCI: Add I/O BAR support to generic pci_mmap_resource_range()
x86/PCI: Use generic pci_mmap_resource_range()
unicore32/PCI: Use generic pci_mmap_resource_range()
sh/PCI: Use generic pci_mmap_resource_range()
parisc: Use generic pci_mmap_resource_range()
mn10300/PCI: Use generic pci_mmap_resource_range()
MIPS: PCI: Use generic pci_mmap_resource_range()
cris/PCI: Use generic pci_mmap_resource_range()
ARM/PCI: Use generic pci_mmap_resource_range()
PCI: Add pci_mmap_resource_range() and use it for ARM64
PCI: Add BAR index argument to pci_mmap_page_range()
PCI: Use BAR index in sysfs attr->private instead of resource pointer
PCI: Add arch_can_pci_mmap_io() on architectures which can mmap() I/O space
PCI: Move multiple declarations of pci_mmap_page_range() to <linux/pci.h>
PCI: Add arch_can_pci_mmap_wc() macro
xtensa/PCI: Do not mmap PCI BARs to userspace as write-through
PCI: Only allow WC mmap on prefetchable resources
PCI: Fix another sanity check bug in /proc/pci mmap
PCI: Fix pci_mmap_fits() for HAVE_PCI_RESOURCE_TO_USER platforms
