David S. Miller fcd26f7ae2 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.
