Subject: [PATCH v2 0/9] PCI, PNP: print resources consistently

These enhance %pR so we can print resource types and flags more easily.
This doesn't really add anything (other than a couple new messages
about host bridge apertures), but hopefully it will make things more
consistent and a bit easier to debug.  Sample change (with "pci=use_crs"):

    -pci 0000:00:03.0: reg 10 32bit mmio: [0xf6000000-0xf6ffffff]
    -pci 0000:00:03.0: reg 14 io port: [0x2400-0x24ff]
    -pci 0000:00:03.0: reg 18 32bit mmio: [0xf5ff0000-0xf5ff0fff]
    -pci 0000:00:03.0: reg 30 32bit mmio pref: [0x000000-0x01ffff]
    +pci_root PNP0A03:00: host bridge window [io  0x0000-0x0cff]
    +pci_root PNP0A03:00: host bridge window [io  0x0000-0x2cfe]
    +pci_root PNP0A03:00: host bridge window [io  0x03b0-0x03bb]
    +pci_root PNP0A03:00: host bridge window [io  0x03c0-0x03df]
    +pci_root PNP0A03:00: host bridge window [mem 0xf5d00000-0xf6ffffff]
    +pci_root PNP0A03:00: host bridge window [mem 0x000a0000-0x000bffff]
    +pci 0000:00:03.0: reg 10: [mem 0xf6000000-0xf6ffffff]
    +pci 0000:00:03.0: reg 14: [io  0x2400-0x24ff]
    +pci 0000:00:03.0: reg 18: [mem 0xf5ff0000-0xf5ff0fff]
    +pci 0000:00:03.0: reg 30: [mem 0x00000000-0x0001ffff pref]

Changes from initial post to v2:
    - tidied vsprintf stack buffer to shrink and compute size more accurately
      (Joe Perches)
    - use %pR for decoding, %pr for "raw" (with type and flags) instead of
      adding %pRt and %pRf
    - split cleanup from printk changes for easier review

I plan some future patches to add more messages and change some dev_dbg()
to dev_info(), so this series is strictly to change the resource formatting.

Bjorn Helgaas (9):
      vsprintf: fix io/mem resource width
      vsprintf: add %pR support for IRQ and DMA resources
      vsprintf: add %pR decoding and %pr for raw struct resource
      PCI: set IORESOURCE_MEM_64 before printing resource
      PCI: trivial bridge resource factorization
      PCI: print resources consistently with %pR
      x86/PCI: print resources consistently with %pR
      ia64/PCI: print resources consistently with %pR
      PNP: print resources consistently with %pR
