kernel/trace/trace.c needs to include at least <linux/irqflags.h>, as
that's where irqs_disabled_flags() is defined.

If there are still other issues with the raw_local_irq(), IMHO they should be
fixed separately.

Hmm, what's this doing in <linux/irqflags.h>:
| #ifdef CONFIG_TRACE_IRQFLAGS_SUPPORT
| ...
| #endif          /* CONFIG_X86 */
                     ^^^^^^^^^^

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
