Fix these kernel compilation warnings:

 WARNING: arch/x86/built-in.o(.cpuinit.text+0x1e07): Section mismatch ...
 WARNING: arch/x86/built-in.o(.cpuinit.text+0x1b10): Section mismatch ...

introduced by:

  de5397ad5b9a: x86, cpu: Enable/disable Supervisor Mode Execution Protection

Change disable_smep from __initdata to __cpuinitdata.
Change setup_smep() from __init to __cpuinit.
