Subject: [ 013/187] powerpc/kvm: sldi should be sld

From: Greg KH <gregkh@...uxfoundation.org>

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michael Neuling <mikey@...ling.org>

commit 2f584a146a2965b82fce89b8d2f95dc5cfe468d0 upstream.

Since we are taking a registers, this should never have been an sldi.
Talking to paulus offline, this is the correct fix.

Was introduced by:
 commit 19ccb76a1938ab364a412253daec64613acbf3df
 Author: Paul Mackerras <paulus@...ba.org>
 Date:   Sat Jul 23 17:42:46 2011 +1000

Talking to paulus, this shouldn't be a literal.
