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:
  [SPARC]: Wire up sys_sync_file_range() into syscall tables.
  [SPARC]: Wire up sys_splice() into the syscall tables.
  [SPARC64]: Update defconfig.
  [SPARC64]: Align address in huge_pte_alloc().
  [SPARC64]: Document the instruction checks we do in do_sparc64_fault().
  [SPARC64]: Make tsb_sync() mm comparison more precise.
