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"
