Merge branch 'parisc-4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux 

Pull parisc updates from Helge Deller:
 "We have two patches in here:

   - The parisc uapi headers have been screwed up since quite some time.
     This patch fixes some bugs (e.g. endianess not respected in
     compat_semid64_ds) and cleans them up (e.g. uid_t was used instead
     of __kernel_uid_t) so that they can be used by userspace again.
     This patch has been reviewed by Arnd Bergmann and is scheduled for
     stable kernel series.

   - Drop the hpux_stat64 struct from stat.h, we do not support HP-UX
     binaries since kernel 4.0"

* 'parisc-4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Fixes and cleanups in kernel uapi header files
  parisc: Drop hpux_stat64 struct from stat.h header file
