Subject: [PATCH 4/8] CRIS: UAPI: use generic sembuf.h

CRIS's sembuf.h is equivalent to the asm-generic version.
Effective diff:

 -#ifndef _CRIS_SEMBUF_H
 -#define _CRIS_SEMBUF_H
 +#ifndef __ASM_GENERIC_SEMBUF_H
 +#define __ASM_GENERIC_SEMBUF_H

 +#include <asm/bitsperlong.h>

  struct semid64_ds {
  	struct ipc64_perm sem_perm;
  	__kernel_time_t	sem_otime;
 +#if __BITS_PER_LONG != 64
  	unsigned long	__unused1;
 +#endif
  	__kernel_time_t	sem_ctime;
 +#if __BITS_PER_LONG != 64
  	unsigned long	__unused2;
 +#endif
  	unsigned long	sem_nsems;
  	unsigned long	__unused3;
  	unsigned long	__unused4;
