Merge tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev
 
Pull libara fixes from Jeff Garzik:

 - Notable regression fix.  Forbid dynamic runtime power management by
   default, due to issues with suspend/resume and hotplug.

   To re-enable, use sysfs.

 - make ata_print_id atomic, due to ref from multiple contexts

 - sata_mv warning fix

 - ata_piix new PCI ID

* tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
  libata: forbid port runtime pm by default, fixing regression
  libata: make ata_print_id atomic
  sata_mv: silence an uninitialized variable warning
  ata_piix: IDE-mode SATA patch for Intel DH89xxCC DeviceIDs
