[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.
