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.
