Re: [PATCH v8 0/3] MR7064: ntdll: Check for invalid GS base in the 64-bit segv_handler.

[William Horvath (＠whrvth)]

v8: 
- added a test
- once again changed to handle non-WoW64 exceptions after Windows testing showed that this is correct
- corrected the commit description
- added a commit to re-enable a previously broken (`#if 0`) test.
