s390: workaround Linux kernel bug in syscall_get_nr
Apparently, arch/s390/include/asm/syscall.h:syscall_get_nr() returns 0
for out-of-range syscall numbers.
This kernel bug is exposed via PTRACE_GET_SYSCALL_INFO interface.
Workaround it by falling back to get_regs() for the zero syscall number.
* linux/s390/check_scno.c: New file.
* linux/s390x/check_scno.c: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
* syscall.c (get_scno): Update comment.
