[09/45] x86, cpu: Fix renamed, not-yet-shipping AMD CPUID feature bit

[Greg KH <gregkh@suse.de>]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Andre Przywara <andre.przywara@amd.com>

commit 7ef8aa72ab176e0288f363d1247079732c5d5792 upstream.

The AMD SSE5 feature set as-it has been replaced by some extensions
to the AVX instruction set. Thus the bit formerly advertised as SSE5
is re-used for one of these extensions (XOP).
Although this changes the /proc/cpuinfo output, it is not user visible, as
there are no CPUs (yet) having this feature.
To avoid confusion this should be added to the stable series, too.
