3.16.51-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Paul Mackerras <paulus@xxxxxxxxxx>
commit 93b2d3cf3733b4060d3623161551f51ea1ab5499 upstream.
The instruction code for xxlor that commit 0016a4cf5582 ("powerpc:
Emulate most Book I instructions in emulate_step()", 2010-06-15)
added is actually the code for xxlnor. It is used in get_vsr()
and put_vsr() and the effect of the error is that if emulate_step
is used to emulate a VSX load or store from any register other
than vsr0, the bitwise complement of the correct value will be
loaded or stored. This corrects the error.
