Build error on s390:
arch/s390/kernel/entry.o: in function `sys_call_table_emu':
>> (.rodata+0x1288): undefined reference to `__s390_'

-149 common _sysctl sys_sysctl compat_sys_sysctl
+149 common _sysctl sys_ni_syscall
150 common mlock sys_mlock sys_mlock
After the patch is integrated, there is a format error in the generated
arch/s390/include/generated/asm/syscall_table.h:
SYSCALL(sys_fdatasync, sys_fdatasync)
SYSCALL(sys_ni_syscall,) /* cause build error */
SYSCALL(sys_mlock,sys_mlock)
According to the guidance of Heiko Carstens, use "-" to fill the empty system call
Similarly, modify tools/perf/arch/s390/entry/syscalls/syscall.tbl.

I get just copies of that file when it gets out of sync, so I suppose
the patch should be just for arch/s390/kernel/syscalls/syscall.tbl and
processed by the s/390 maintainer?
