Merge branch 'parisc-4.13-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller...

Pull parsic fixes from Helge Deller:

 - Our cache flushing code ran into a BUG in case context is not
   current. Fix it by flushing the whole cache in such rare situations
   (by Dave Anglin).

 - Fix a "sleeping function called from invalid context BUG" in our
   pdc_stable driver by rearranging our locks (by James Bottomley)

 - The thread and irq stacks require more than 16 KB since kernel 4.11.
   Increase both to 32 KB.

 - Define CONFIG_CPU_BIG_ENDIAN unconditionally on parisc to avoid wrong
   behaviour in qrwlock functions (by Babu Moger).
