Subject: [PATCH] tracing: fix a build error on alpha and m68k

From: Frederic Weisbecker <[email-masked]>

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_generic_entry_update':
kernel/trace/trace.c:658: error: implicit declaration of function 'irqs_disabled_flags'
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'
kernel/trace/trace.c: In function 'trace_die_handler':
kernel/trace/trace.c:3039: error: 'DIE_OOPS' undeclared (first use in this function)

Build error on m68k:

Include it on kernel/trace/trace.c
