91 of ~160 wrapped syscalls produce compile time error without it on
arm64:
arch/arm64/kernel/sys_ilp32.c:59:35: error: ‘compat_sys_io_destroy’ undeclared here (not in a function)
#define __SC_WRAP(nr, sym) [nr] = compat_##sym,
^
include/uapi/asm-generic/unistd.h:39:1: note: in expansion of macro ‘__SC_WRAP’
__SC_WRAP(__NR_io_destroy, sys_io_destroy)
^
I think, it's better to leave it as is...

It turns even better because most syscalls are just wrappers like:
SYSCALL_DEFINE(foo)
{
do_foo();
}
And with your approach GCC inlines sys_foo() that saves few cpu
cycles and stack:
<SyS_truncate>: <compat_SyS_truncate>
stp x29, x30, [sp,#-16]! stp x29, x30, [sp,#-16]!
mov x29, sp mov x29, sp
bl ca8 <do_sys_truncate> sxtw x1, w1
ldp x29, x30, [sp],#16 bl ca8 <do_sys_truncate>
ret ldp x29, x30, [sp],#16
nop ret
Thank you for adwise. See below what turned out.
Build-tested on s390, x86_64.
Yury.
