[PATCH -next] MIPS: traps: Add missing include file

[Guenter Roeck <linux@roeck-us.net>]

Commit 05155ddc2617 ("MIPS: get rid of 'kgdb_early_setup' cruft")
removed the include of linux/kgdb.h from arch/mips/kernel/traps.c.
This results in

arch/mips/kernel/traps.c: In function 'show_stack':
arch/mips/kernel/traps.c:204:14: error: 'kgdb_active' undeclared
arch/mips/kernel/traps.c: In function 'do_trap_or_bp':
arch/mips/kernel/traps.c:877:2: error:
		implicit declaration of function 'kgdb_ll_trap'

when building mips:allmodconfig.
