By including <asm/processor-flags.h> we're allowed to use
X86_CR4_PGE instead of numeric constant.
md5 sums of compiled files are differ due to this inclusion
but .text section remains the same.

If anyone has an objection on this patch - just drop it please.
I'm not sure but this could have a side effect in case of future
<asm/processor-flags.h> modifications so it would require
__ASSEMBLY__ preprocessor directive.
