* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: (26 commits)
  [SPARC64]: Fix UP build.
  [SPARC64]: dr-cpu unconfigure support.
  [SERIAL]: Fix console write locking in sparc drivers.
  [SPARC64]: Give more accurate errors in dr_cpu_configure().
  [SPARC64]: Clear cpu_{core,sibling}_map[] in smp_fill_in_sib_core_maps()
  [SPARC64]: Fix leak when DR added cpu does not bootup.
  [SPARC64]: Add ->set_affinity IRQ handlers.
  [SPARC64]: Process dr-cpu events in a kthread instead of workqueue.
  [SPARC64]: More sensible udelay implementation.
  [SPARC64]: SMP build fixes.
  [SPARC64]: mdesc.c needs linux/mm.h
  [SPARC64]: Fix build regressions added by dr-cpu changes.
  [SPARC64]: Unconditionally register vio_bus_type.
  [SPARC64]: Initial LDOM cpu hotplug support.
  [SPARC64]: Fix setting of variables in LDOM guest.
  [SPARC64]: Fix MD property lifetime bugs.
  [SPARC64]: Abstract out mdesc accesses for better MD update handling.
  [SPARC64]: Use more mearningful names for IRQ registry.
  [SPARC64]: Initial domain-services driver.
  [SPARC64]: Export powerd facilities for external entities.
