Helge Deller e213cce42b parisc: Unbreak handling exceptions from kernel modules 
[ Upstream commit 2ef4dfd9d9 ]

Handling exceptions from modules never worked on parisc.
It was just masked by the fact that exceptions from modules
don't happen during normal use.

When a module triggers an exception in get_user() we need to load the
main kernel dp value before accessing the exception_data structure, and
afterwards restore the original dp value of the module on exit.
