Subject: [PATCH] MIPS: smp-cmp: Use right include for task_struct
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

When task_struct was moved, this MIPS code was neglected. Evidently
nobody is using it anymore. This fixes this build error:

In file included from ./arch/mips/include/asm/thread_info.h:15:0,
                 from ./include/linux/thread_info.h:37,

                 from ./arch/mips/include/generated/asm/current.h:1,
                 from ./include/linux/sched.h:11,
                 from arch/mips/kernel/smp-cmp.c:22:
