Tom Lendacky 872cbefd2d x86/cpu/AMD: Add the Secure Memory Encryption CPU feature ... Update the CPU features to include identifying and reporting on the Secure Memory Encryption (SME) feature. SME is identified by CPUID 0x8000001f, but requires BIOS support to enable it (set bit 23 of MSR_K8_SYSCFG). Only show the SME feature as available if reported by CPUID, enabled by BIOS and not configured as CONFIG_X86_32=y.
