Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  Void 5.8.18_1 x86_64 GenuineIntel notuptodate rF
* package:  
  igt-gpu-tools-1.25_2

### Expected behavior

intel_reg_checker works w/o segment fault

### Actual behavior

intel_reg_checker segment fault with kernel msg:

```
[339369.109908] intel_reg_check[29631]: segfault at 1d3f6 ip 000000000001d3f6 sp 00007ffe69bfbcb8 error 14 in intel_reg_checker[55d66cf5c000+1000]
[339369.109920] Code: Unable to access opcode bytes at RIP 0x1d3cc.
```

I did some initial debugging, it seems there's something wrong with F16C cpu feature, here's call stack:

```
Program terminated with signal SIGSEGV, Segmentation fault.
