sparc64: Fix DAX handling via userspace access from kernel. If we do a userspace access from kernel mode, and get a data access exception, we need to check the exception table just like a normal fault does. The spitfire DAX handler was doing this, but such logic was missing from the sun4v DAX code. Reported-by: Dennis Gilmore <dgilmore@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
