Revert "sched/x86_64: Don't save flags on context switch"
This reverts commit: 2c7577a75837 ("sched/x86_64: Don't save flags on context switch") It was a nice speedup. It's also not quite correct: SYSENTER enables interrupts too early. We can re-add this optimization once the SYSENTER code is beaten into shape, which should happen in 4.3 or 4.4.
