Hi Cyril.
Thanks for you quickly response.

Some of your point has been fixed. Some are not:
1. I'm using gcc (GCC) 11.4.1 20230605, `addr` without initialization would output some warnings.
2. I read the manpage of arch_prctl, the ARCH_GET_CPUID seems return the flag, instead of storing `addr`:
```
ARCH_GET_CPUID (since Linux 4.12)
Return the setting of the flag manipulated by ARCH_SET_CPUID as the result of the system call (1 for enabled, 0 for
disabled). addr is ignored.
```
I'm not sure if this is a problem of my environment.
