Accordingly, we already have S/U32_MAX for their max values.
So, we should not add (U)INT32_MAX to any more.

s redefined __x32_sys_* to __x64_sys_* because there is
no stub like __x32_sys_*.
I think defining as follows is sensible and cleaner.
__SYSCALL_COMMON(nr, sym) --> __x64_
__SYSCALL_X32(nr, sym) --> __x64_
The ugly #define __x32_sys_* will go away.

As of v5.11-rc1, 12 architectures duplicate similar shell scripts in
order to generate syscall table headers. My goal is to unify them into
the single scripts/syscalltbl.sh.
This commit converts ia64 to use scripts/syscalltbl.sh.

without changing the functionality.
Masahiro Yamada (27):
scripts: add generic syscalltbl.sh
x86/syscalls: fix -Wmissing-prototypes warnings from COND_SYSCALL()
x86/build: add missing FORCE and fix 'targets' to make if_changed work
x86/entry/x32: rename __x32_compat_sys_
);
| ^~~~
...
__SYS_STUB0() and __SYS_STUBx() defined a few lines above have forward
declarations. Let's do likewise for __COND_SYSCALL() to fix the
warnings.

Add an empty file if it is missing in arch/$(SRCARCH)/.
