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:

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