So, the change is purely to get past the `if (vendor == X86_CPU_VENDOR_OTHER) { return; }` check? And then the generic `GNUTLS_x86_cpuid_s[1] & bit_AES` just works?

> This fallback to the software provider (Nettle wrapper) could lead to numerical issues or crashes (e.g., divide-by-zero) in certain environments like Photoshop.

Could you please elaborate on that?
