As Garret proposed, can you please apply the following Patch and see if it
solves your build problem. I get the following instructions from 2.6.31
kernel sources:

linux-2.6.31/arch/s390/include/asm/unistd.h:
208 #define __NR_remap_file_pages   267
209 /* Number 268 is reserved for new sys_mbind */
210 /* Number 269 is reserved for new sys_get_mempolicy */
211 /* Number 270 is reserved for new sys_set_mempolicy */
212 #define __NR_mq_open            271
