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

* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6:
  [SPARC64]: Optimize fault kprobe handling just like powerpc.
  [SPARC]: Wire up utimensat syscall.
  [SPARC64]: Fix request_irq() ignored result warnings in PCI controller code.
  [SPARC64]: Kill asm-sparc64/pbm.h
  [ATYFB]: Fix sparc includes.
  [QLA2XXX]: Fix build on sparc.
  [SPARC64]: Removal of trivial pci_controller_info uses.
  [SPARC64]: Move index info pci_pbm_info.
  [SPARC64]: Move {setup,teardown}_msi_irq into pci_pbm_info.
  [SPARC64]: Move pci_ops into pci_pbm_info.
  [SPARC64] SBUS: Error interrupt registry cleanups.
  [SPARC64] PCI: Use root list of pbm's instead of pci_controller_info's
  [SPARC64] PCI: Kill PROM_PCIRNG_MAX and PROM_PCIIMAP_MAX.
  [SPARC64] PCI: Use common routine to fetch PBM properties.
