* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6:
  [SPARC64]: fix section mismatch warning in mdesc.c
  [SPARC64]: fix section mismatch warning in pci_sunv4
  [SPARC64]: Stop using drivers/char/rtc.c
  [SPARC64]: Convert parport to of_platform_driver.
  [SPARC]: Implement fb_is_primary_device().
  [SPARC64]: Fix virq decomposition.
  [SPARC64]: Use KERN_ERR in IRQ manipulation error printks.
  [SPARC64]: Do not flood log with failed DS messages.
  [SPARC64]: Add proper multicast support to VNET driver.
  [SPARC64]: Handle multiple domain-services-port nodes properly.
  [SPARC64]: Improve VIO device naming further.
  [SPARC]: Make sure dev_archdata is filled in for all devices.
  [SPARC]: Define minimal struct dev_archdata, similarly to sparc64.
  [SPARC]: Fix serial console device detection.
