Merge branch 'parisc-4.6-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc ftrace fixes from Helge Deller:
 "This is (most likely) the last pull request for v4.6 for the parisc
  architecture.

  It fixes the FTRACE feature for parisc, which is horribly broken since
   quite some time and doesn't even compile.  This patch just fixes the
  bare minimum (it actually removes more lines than it adds), so that
  the function tracer works again on 32- and 64bit kernels.

  I've queued up additional patches on top of this patch which e.g. add
  the syscall tracer, but those have to wait for the merge window for
  v4.7."
