Merge branch 'parisc-3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux 

Pull parisc update from Helge Deller:
 "The major change in here is the removal of the old HP-UX compat code
  which should have made it possible to load and execute 32-bit HP-UX
  binaries on PA-RISC Linux.  Since it was never functional and since
  nobody cares about old 32-bit HPUX binaries any longer, it's now time
  to free up 3200 lines of kernel code (CONFIG_HPUX and
  CONFIG_BINFMT_SOM).

  Other than that we wire up the execveat() syscall, fix sparse errors
  and have some whitespace cleanups"

* 'parisc-3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  fs/binfmt_som: Drop kernel support for HP-UX SOM binaries
  parisc: Remove unused function
  parisc: macro whitespace fixes
  parisc/uaccess: fix sparse errors
  parisc: hpux - Remove HPUX syscall numbers
  parisc: hpux - Remove hpux gateway page
  parisc: hpux - Delete files in hpux subdirectory
  parisc: hpux - Do not compile hpux subdirectory
  parisc: hpux - Drop support for HP-UX binaries
  parisc: Add error checks when building up signal trampoline handler
  parisc: Wire up execveat syscall
