Merge branch 'parisc-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parsic updates from Helge Deller:
 "This patchset includes two major fixes which are both scheduled for
  stable:

  First, __ARCH_SI_PREAMBLE_SIZE was defined with a wrong value.
  Second, huge page pte and TLB changes needed protection with a
  spinlock.  Other than that there are just some trivial optimizations
  and cleanups"
