Subject[PATCH 3.2 074/115] parisc: Avoid function pointers for kernel exception routines
3.2.80-rc1 review patch.  If anyone has any objections, please let me know.


From: Helge Deller <>

commit e3893027a300927049efc1572f852201eb785142 upstream.

We want to avoid the kernel module loader to create function pointers
for the kernel fixup routines of get_user() and put_user(). Changing
the external reference from function type to int type fixes this.

This unbreaks exception handling for get_user() and put_user() when
called from a kernel module.
