Merge branch 'misc.sparc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull sparc syscall cleanups from Al Viro:
 "sparc syscall stuff - killing pointless wrappers, conversions to
  {COMPAT_,}SYSCALL_DEFINE"

* 'misc.sparc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  sparc: get rid of asm wrapper for nis_syscall()
  sparc: switch compat {f,}truncate64() to COMPAT_SYSCALL_DEFINE
  sparc: switch compat pread64 and pwrite64 to COMPAT_SYSCALL_DEFINE
  convert compat sync_file_range() to COMPAT_SYSCALL_DEFINE
  switch sparc_remap_file_pages() to SYSCALL_DEFINE
  sparc: get rid of memory_ordering(2) wrapper
  sparc: trivial conversions to {COMPAT_,}SYSCALL_DEFINE()
  sparc: bury a zombie extern that had been that way for twenty years
  sparc: get rid of remaining SIGN... wrappers
  sparc: kill useless SIGN... wrappers
  sparc: get rid of sys_sparc_pipe() wrappers
