Merge branch 'parisc-4.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc fixes from Helge Deller:
 "Some final updates and fixes for this merge window for the parisc
  architecture. Changes include:

   - Fix boot problems with new memblock allocator on rp3410 machine

   - Increase initial kernel mapping size for 32- and 64-bit kernels,
     this allows to boot bigger kernels which have many modules built-in

   - Fix kernel layout regarding __gp and move exception table into RO
     section

   - Show trap names in crashes, use extable.h header instead of
     module.h"
