Just because I'm crazy, can you double-check that you applied my patch
and booted the right kernel?

Because that NX error *really* looks like the call to setup_smep(),
and the eip still very much looks like something jumped to the
"__init" region, not the "__cpuinit" region.

That backtrace really still looks like the same thing.

Oh, and you should do

-static int disable_smep __initdata;
+static int disable_smep __cpuinitdata;

too, I guess. Not that it should matter for this particular oops.
