Subject: Merge branch 'pci/sysfs'
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8b3a73b4fe107705f2a11f413a0516119632ea40;p=thirdparty%2Flinux.git

Merge branch 'pci/sysfs'

- Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize' attributes
  (Krzysztof Wilczyński)

- Convert PCI resource files to static attributes to avoid races that cause
  'duplicate filename' warnings and boot panics (Krzysztof Wilczyński)

- Remove pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files(),
  which are obsolete after converting to static attributes (Krzysztof
  Wilczyński)

- Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource mmap
  path to match the generic path (Krzysztof Wilczyński)

- Convert sysfs 'legacy_io' and 'legacy_mem' to static attributes
  (Krzysztof Wilczyński)

- Remove pci_create_legacy_files() and pci_sysfs_init(), which are obsolete
  after converting to static attributes (Krzysztof Wilczyński)

- Expose sysfs 'resourceN_resize' attributes only on platforms with PCI
  mmap (Krzysztof Wilczyński)

- Use kstrtobool() to parse the 'rom' attribute input to avoid the
  unexpected behavior of enabling the ROM when writing '0' with no trailing
  newline (Krzysztof Wilczyński)
