From: Sean Christopherson <seanjc@google.com> Add SGX1 and SGX2 feature flags, via CPUID.0x12.0x0.EAX, as scattered features. As part of virtualizing SGX, KVM will expose the SGX CPUID leafs to its guest, and to do so correctly needs to query hardware and kernel support for SGX1 and SGX2.
This commit message is missing reasoning behind scattered vs. own word. Please just document the reasoning, that's all. /Jarkko
