tracing: fix a build error on alpha

When tracing is enabled, some arch have included <linux/irqflags.h> on their <asm/system.h> but others like alpha or m68k don't.

Build error on alpha:

kernel/trace/trace.c: In function 'tracing_cpumask_write':
kernel/trace/trace.c:2145: error: implicit declaration of function 'raw_local_irq_disable' kernel/trace/trace.c:2162: error: implicit declaration of function 'raw_local_irq_enable'

Tested on Alpha through a cross-compiler (should correct a similar issue on m68k).

Already fixed.

Note that it's already fixed because the patch you are replying to (and which was sent 16 days ago) is already upstream:
