[LTP] compile fails for libcpuset.c on SLES-11 s390x with ltp-full-20090930

Trying to build ltp-full-20090930 on SLES-11.  The "make all" gets the
following:

...

As far as I can tell the architecture does not support get_mempolicy and
set_mem_policy.

Here are the configure logs and stuff from the build attempt:

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...

This is even simplier. Just look into testcases/kernel/include/ directory and
add "get_mempolicy xxx" and "set_mempolicy yyy" into corresponding file (for
you it's s390.in). The build porcess should generate file
linux_syscall_numbers.h for you. Anyway I'm preparing patch fixing this.
