Subject[PATCH 00/17] PCI resource mmap cleanup
Date
This started out as a fairly trivial "add pci_mmap_page_range() for 
ARM64" patch. But pci_mmap_page_range() is a vile interface, taking
"user visible" resource addresses converted with pci_resource_to_user()
on those platforms unlucky enough to use that... and even in the *sane*
sysfs-based mmap method, we convert through user addresses to call the
platform-specific method.

In most cases there's just no need for any of this crap. We can migrate
most architectures to a generic implementation without much thought,
and the few that aren't converted in this series can probably be added
fairly easily too but need a little more arch-specific attention.

Utterly untested for now; I'll do some testing while I deal with the
inevitable bikeshedding.

David Woodhouse (17):
pci: Fix pci_mmap_fits() for HAVE_PCI_RESOURCE_TO_USER platforms
pci: Fix another sanity check bug in /proc/pci mmap
pci: Only allow WC mmap on prefetchable resources
pci: Add arch_can_pci_mmap_wc() macro
pci: Move multiple declarations of pci_mmap_page_range() to <linux/pci.h>
pci: Add HAVE_PCI_MMAP_IO to architectures which can mmap() I/O space
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
arm: Use generic pci_mmap_resource_range()
cris: Use generic pci_mmap_resource_range()
mips: Use generic pci_mmap_resource_range()
mn10300: Use generic pci_mmap_resource_range()
parisc: Use generic pci_mmap_resource_range()
sh: Use generic pci_mmap_resource_range()
unicore: Use generic pci_mmap_resource_range()
arm64: Do not expose PCI mmap through procfs
