.cpu_features is exactly the same compare to 745/755 (750CXe 3.1, PVR 0008
3311, was probed as 745/755). However, there is a small difference: It now
calls __setup_cpu_750cx instead of __setup_cpu_750.
This end up calling setup_750cx which looks like to disable NAP.
Well, I did not notice anything before and after the patch. It's more
'comsetic': cpuinfo shows the correct cpu name. :-)
