x86 cleanup: suspend_asm_64.S - use X86_CR4_PGE instead of numeric value
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. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
