Merge tag 'asm-generic-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull arch/sh syscall table scripting from Arnd Bergmann:
 "I worked with Firoz Khan to change all architectures to have their
  system call tables (syscall.S and asm/unistd.h) generated by a script
  from a more readable input file the same way that we already had on
  x86, s390 and arm.

  I offered to take those conversions through the asm-generic tree that
  did not get picked up by the architecture maintainers, and fortunately
  all but one have now been accepted into arch maintainer trees, so this
  branch only contains the conversion for arch/sh/, with permission from
  Rich.

  The conversion does not include the old 64-bit sh5 architecture, which
  has never shipped and not even compiled in a long time. The table in
  include/uapi/asm/unistd.h is also not included here, as Firoz is still
  working on that one, it will have to wait for the next following merge
  window, hopefully together with the addition of the 64-bit time_t
  system calls for the y2038 work that led to the system call table
  rework"

* tag 'asm-generic-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
  sh: generate uapi header and syscall table header files
  sh: add system call table generation support
  sh: add __NR_syscalls along with NR_syscalls
