Merge branch 'pci/sysfs'

Browse source 
- In pci_write_legacy_io(), avoid out-of-bounds reads from the user buffer
  and fix incorrect ioport write data (1-byte writes on little-endian
  powerpc, 2- and 4-byte writes on big-endian powerpc) (Krzysztof
  Wilczyński)

- In pci_read_legacy_io(), fix incorrect ioport read data for 2- and 4-byte
  reads on big-endian powerpc (Krzysztof Wilczyński)

- Fix I/O port accessor argument order in Alpha pci_legacy_write()
  (Krzysztof Wilczyński)

- Avoid spurious runtime PM wakeup on config space accesses that are
  outside config space and fail before reaching PCI (Krzysztof Wilczyński)

- Return -EINVAL, not -ENODEV, for mmap of I/O BAR that fails because the
  arch doesn't support it, as we do for procfs (Krzysztof Wilczyński)

- Check for LOCKDOWN_PCI_ACCESS for legacy_io and legacy_mem, as we do for
  other config space accessors (Krzysztof Wilczyński)

- Tidy static resource attribute names and macros that build them
  (Krzysztof Wilczyński)
