* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: (67 commits)
  [SCSI] SUNESP: Complete driver rewrite to version 2.0
  [SPARC64]: Convert PCI over to generic struct iommu/strbuf.
  [SPARC]: device_node name constification fallout
  [SPARC64]: Convert SBUS over to generic iommu/strbuf structs.
  [SPARC64]: Add generic iommu and strbuf structs to iommu.h
  [SPARC64]: Consolidate {sbus,pci}_iommu_arena.
  [SPARC]: Make device_node name and type const
  [SPARC64]: constify some paramaters of OF routines
  [TIGON3]: of_get_property() returns const.
  [SPARC64]: Fix PCI rework to adhere to of_get_property() const return.
  [SPARC64]: Document and fix calculation of pages_avail.
  [SPARC64]: Make sure pbm->prom_node is setup easly enough in psycho.c
  [SPARC64]: Use bootmem_bootmap_pages() in choose_bootmap_pfn().
  [SPARC64]: Add proper header file extern for cmdline_memory_size.
  [SPARC64]: Kill sparc_ultra_dump_{i,d}tlb()
  [SPARC64]: Use DECLARE_BITMAP and BITS_TO_LONGS in mm/init.c
  [SPARC64]: Give move verbose show_mem() output just like i386.
  [SPARC64]: Mark show_mem() printk's with KERN_INFO.
  [SPARC64]: Kill kvaddr_to_phys() and friends.
  [SPARC64]: Privatize sun4u_get_pte() and fix name.
