Merge tag 'asm-generic-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic cleanup from Arnd Bergmann:
 "I have only one patch for asm-generic in this release, this one is
  from James Hogan and updates the generic system call table for
  renameat2 so we don't need to provide both renameat and renameat2 in
  newly added architectures"

* tag 'asm-generic-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
  asm-generic: Drop renameat syscall from default list
