Merge tag 'powerpc-4.17-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc...

Pull powerpc fixes from Michael Ellerman:
 "One fix for an actual regression, the change to the SYSCALL_DEFINE
  wrapper broke FTRACE_SYSCALLS for us due to a name mismatch. There's
  also another commit to the same code to make sure we match all our
  syscalls with various prefixes.

  And then just one minor build fix, and the removal of an unused
  variable that was removed and then snuck back in due to some rebasing.

  Thanks to: Naveen N. Rao"
