Merge branch 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6 

* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6:
  [SPARC64]: Fill holes in hypervisor APIs and fix KTSB registry.
  [SPARC64]: Fix two bugs wrt. kernel 4MB TSB.
  [SPARC]: Mark as emulating cmpxchg, add appropriate depends for DRM.
  [SPARC]: Emulate cmpxchg like parisc
  [SPARC64]: Fix _PAGE_EXEC_4U check in sun4u I-TLB miss handler.
  [SPARC]: Linux always started with 9600 8N1
  [SPARC64]: arch/sparc64/time.c doesn't compile on Ultra 1 (no PCI)
  [SPARC64]: Eliminate NR_CPUS limitations.
  [SPARC64]: Use machine description and OBP properly for cpu probing.
  [SPARC64]: Negotiate hypervisor API for PCI services.
  [SPARC64]: Report proper system soft state to the hypervisor.
  [SPARC64]: Fix typo in sun4v_hvapi_register error handling.
  [SCSI] ESP: Kill SCSI_ESP_CORE and link directly just like jazz_esp
  [SCSI] jazz_esp: Converted to use esp_core.
  [SPARC64]: PCI device scan is way too verbose by default.
  [SERIAL] sunzilog: section mismatch fix
  [SPARC32]: Removes mismatch section warnigs in sparc time.c file
  [SPARC64]: Don't be picky about virtual-dma values on sun4v.
  [SPARC64]: Kill unused DIE_PAGE_FAULT enum value.
  [SCSI] pluto: Use wait_for_completion_timeout.
