The constant is defined for the platform, but not with the correct name:
/usr/src/linux/arch/s390/kernel/syscalls.S:NI_SYSCALL
/* 269 sys_get_mempolicy */
/usr/src/linux/arch/s390/include/asm/unistd.h:/* Number 269 is
reserved for new sys_get_mempolicy */
/usr/src/linux/arch/s390/include/asm/unistd.h:#define __IGNORE_get_mempolicy
This needs to be added to testcases/kernel/include/generate.sh for
linux_syscall_numbers.h, or an arch specific #ifdef should be added
for that test / to an autoconf test that would automatically determine
whether or not your platform had a usable get_mempolicy syscall.
Hope that helps describe what needs to take place next...
